Thai Diamond Bar B Q

This review is for their boba services. I have not yet been able to eat here. Still, their boba drinks are pretty good. My sister and I came here 10 minutes before they closed and we’re kind enough to do four drink orders in less than 7 minutes.
Their Thai tea is also one of the best I have tasted, and checking in allows you to get a free one. Try out their taro too!

Had a wonderful dinner at this restaurant. We shared 5 separate dishes. All were excellent. The rice and the noodles dishes were also excellent. The Thai beer they had was very good. All and all a great place. Will be back.

Service: I came here around 830PM on a Friday and there were about four other tables that were being waited on. The server sat us down, placed menus on our table, and never returned. My friend asked for waters, the waitress brought the waters, and again never returned to take our order. We flagged her down and gave her the order, but did not understand some of our order (English was not her first language). Waitress was inattentive.
Food: The chicken salad was not pleasing to the eye as the chicken looked uncooked and was cold. However, steam appeared to have been rising from the chicken, which left me confused. Pineapple rice w/​shrimp and tofu pad Thai were good.
Other: Good music, two televisions with subtitles, the restaurant was clean.

Love this restaurant… you got to try !!

This place never fails. I believe they are family owned. Very sweet people.
Ordered for pick up. The food was ready in 25 minutes.
Ordered spare ribs, my favorite. The meat falls off the bone and has great flavor.
Chicken pad Thai.
Satee, very tender beef. Goes really great with their peanut sauce.
Egg rolls cute baby ones. They are great.
And shrimp fried rice is amazing with everything.
Love this place!!!

Thai food is not something i’d associate Rancho Cucamonga with because the city is more known to having all the chain restaurants you can imagine, but I thought I give this place a try since my friend really wanted thai food. We came in at 230~, it was a weekday and it wasn’t crowded, but I didn’t mind at all.
They have happy hour M-​F; A whole menu that is $ 6.50! Pretty good bargain and decent portion. I ordered the Pad Thai Chicken, it came out pretty solid. It also comes with a side of soup! The noodles were chewy and not overcooked, and flavorings are pretty standard, nothing too special but still very tasty. [A bit too over sauced for my liking though]
*If you check-​in on Unilocal,you get a free thai tea, so don’t forget to do that!
I’d probably come back to try out their other lunch specials! It’s worth giving a try if you need a quick fix for thai-​food.

I LOVE THE FOOD HERE.
*disclaimer* I’m a fairly new celica so I like to include a little bit of both. Also, I personally have different categories for rating 1 – 5. This restaurant I would categorize as casual dining. If you like to read my reviews that’s how I like to keep things consistent. I rate each place on it’s category, rather than comparing them to categories outside their reach. (Can’t compare casual dining to upscale dining)
I’ve been coming to this place for something like… my whole life.
As a disclaimer, I eat the same foods ALL the time so I only know of a few other options.
Also of the foods I will list I have NEVER had a gluten reaction and I’m a celiac! All you need to do is make sure to order any fried rice options with NO soy sauce and honestly the flavor is not compromised. (you could ask them to cook it in a clean pan to be safe)
We always get the following options:
Tom kha khai (sorry if I spelled that wrong) chicken coconut soup! Mild.
Combination fried rice (NO SOY SAUCE* for gluten free)
beef and chicken skewer dinner with EXTRA peanut sauce (this comes with their orange rice I absolutely
and sometimes: bbq half chicken
You won’t go wrong with these dishes.
To be fair, I did try the duck curry… and I did not recommend it.
My sister loved the orange chicken (NOT gluten free)
And btw, although they don’t always speak the best English the service is great. They are super friendly, they are on-​time, they try to relate to us (our family has been going for a long time)
If you’re looking for a casual, comfortable, tasty dining experience, this place is the place to be! The prices on the dishes are about right for average thai cuisine, sometimes cheaper ranging $ 6-​$ 11/​dish.
Tip: do consider buying dishes to share, that’s the best way to eat their food. It’s not exactly an individual meal type of thing.

Best Thai restaurant I know around here!
I have been coming to this place for a while now. The customer service and food are great. I always order the BBQ Pork Spare Ribs, Pad See Ew with chicken, and Pad Thai with shrimp when I eat here. The thai tea with boba is bomb too!
Give this place a try, you will love it.

Ordered the Pra King BBQ chicken and pad Thai lunch special. Wasn’t too impressed with the chicken plate, wasn’t bad though. The pad Thai served was a good amount for the lunch special portion… so that’s a plus Thai T boba was yummy. Might give this place another shot in the future.

I liked it better this second time around. I dined in this time and had the chicken coconut soup, shrimp chow mein, and orange chicken. They were all really tasty and the portions were filling. The atmosphere is really nice, the staff is friendly, and the food has a homemade feel and taste.

Finally tried Thai Diamond BBQ and we were not disappointed. The broth of the chicken in coconut milk soup was so creamy and yummy. The hub liked his S-​1 bbq chicken and I tried the S-​7 Dearest crab and really liked that too. We also shared the pad see-​ew and the hub thinks it’s better than other restaurants’. Service was also quick and friendly.

Been a customer for years. Take out portions literally ½ of what they used to be, while the prices continue to increase w/​o warning. When I got home and saw the portions, I called to complain. Owners stated they were unaware of the decrease in food portions because food is prepared by an OFFSITE vendor and nothing can be done. They lost a customer.

It wasn’t really anything special to me. Basically over priced dishes, most of which you can get at any cheap Chinese food place. Like beef and broccoli… Orange chicken… Fried rice… Etc. My dish of vegetables were barely cooked. My beef panang tasted pretty good but I prefer the way it tastes at other Thai restaurants. Service was very nice and the place has a nice atmosphere. It smelled a little too strong of incense which caused a little headache. It wasn’t terrible but it wasn’t all that good so we won’t be back.

We have been here twice and enjoyed it a lot.
So far we have tried the following:
Sa-​te dinner 9.95
Pad Thai with beef
Spicy mint noodles
Bbq pork spareribs dinner 9.95
Wontons and fried calamari
Great taste and fast and friendly service. We have been using the $ 20 off coupons that are available via Amazon Local without problems.
I’d recommend this place!

I really enjoyed their BBQ Chicken.
Ive been coming here for 15years!
Definitely recommend this place tgeir BBQ Chicken is not like every Thai restaurant. :)

I am here allll the time but forget to check in! Anyways I love this place, great food & great prices. I usually come at or around lunch time for the lunch special but even if you don’t come for lunch the prices are still really good! They also give good portions of food!

My favorite Thai place since the early 2000’s. I grew up eating here and I love it so much. Glad I took my mother and my family and bf here for Mother’s Day.

Our company started to order lunch from this place every Tuesday for about a month, it’s not our first time to order lunch, and I have been dining here as well. With that said, we know the regular portion from our orders.
Today, 3÷17÷2015, we ordered 5 different entrées from this place for lunch. One of them (Pad See Ew) came with extremely small portion. It was about ¹⁄₃ ~ ½ of portion compared to the other 4 entrées. It was very obvious, and all people in our office agreed that the portion of this one was noticeably smaller than others, and orders we had in the past.
I thought to make a phone call to complain (without asking money back or anything, just to «so they know» type of complain). I was in a good mood, and I was not to call for a fight. However, the lady from the other end kept telling me that the portion has no problem and make it our fault to even complain about it. She tried to explain that the portion is all the same when they prepared the food. Well, lady, you can say whatever you want to say to defend your restaurant, but the portion was small no matter what you say! And if you were telling me this, that means you implied that I was lying to you.
She even made a comment that «one entrée can’t feed 5 people»? WTF! We ordered 5 entrées, ok? We didn’t just order 1 to share. You know what? In this kind of situation, just apologies and let us know that you will make sure the portion is going to be right for the next time. Why explain and talk back to me? I didn’t ask for money back, I didn’t ask for extra entrée for free. What do you have to lose?
You know what? From now on, no more order from us in the future, and you get a 1 star review. That’s what you get for talking back to me!
Let’s see the picture, you guys be the judge! You can even see the bottom of the container, it means it wasn’t even a complete layer of food. That’s how little portion this entrée was! (The other 4 entrées were all loaded and filled up) I wouldn’t waste my time to take a picture, make a phone call, and write this review if it was OK!
Oh! Forgot to mention how the phone conversation ends. She said to me «I will let the owner know, and if you have nothing else, I have other customer waiting on the line» Click, she hang up on me. This is the worst customer service I ever seen!

This review is solely based off of my To-​Go experience with them, not Dine-​In.
MOST AUTHENTIC TASTING THAI FOOD AROUND! Me and my mom were craving Thai food on our lunch break from work, and my mom’s friend/​coworker who used to work at Thai Diamond recommended us to try it out.
Since we were at work I ordered to-​go/​pick-​up on the phone. My mom ordered the Beef Larb in «spicy» and the beef fried rice in «spicy» also then with 2 Thai ice tea bobas. The man taking the order said it will take about 15 minutes which is really fast in my opinion. He told me the total would be $ 25. What a deal! So I went to go pick up my order and my food was wrapped and ready for me to take but they made the boba on site when I arrived. Which I like because it is guaranteed fresh. Service was friendly, and understanding, especially when I ran back to them from my car because I forgot to ask them for their spicy sauce my mother requested. The man saw me running after I opened the door and ask, «yes? did you need anything else?» LOL
Now it is time to eat the meal! And let me tell you this, the portion was huge and everything tasted so fresh and authentic, my mouth is watering while writing this review as I reminiscence about the spicy beef larb! When you request for spicy, they do not hold back, it was a little too hot for me to handle but nonetheless still satisfying. I will be eating here again soon, hopefully this time to dine in!

This is a random out of the way area for me, but we were a little early for the ontario airport an wanted to eat some food.
Ordered — Beef salad — it had seeds a lot of seeds in it an was HOT. The flavors were ok and the portion was fine, just beware of the BURN! lol!
Pad won sen — glass noodle stir fry dish I was pleasantly surprised that it was not too bad.
Overall, they had a lot to choose from and in this neck of the woods, its not like there is a thai restaurant on every block to choose from for the best thai food ever. This place will certainly hold you over and fill you up without breaking the bank.
