Mustard’s Last Stand

As a hot dog addict I’m constantly craving a fix. Mustard’s Last Stand; conveniently located between campus and Pearl street is the perfect restaurant for a quick, fresh, hot dog with friendly service and expansive menu options.
I always stick with the classic hot dog and I’ve never been disappointed. Definitely becoming a regular at this joint!

I fly back from LA just to come home to this hot dog! The Jumbo char dog tastes better than any hotdog in Chicago and my mom used to live in Chicago and she agrees with me!
This is going to sound like a great joke to Freud but I dream of these hotdogs they are so amazing!!!

A plain hot dog is $ 4.50 … You can buy a pack for that much! It would of been maybe worth $ 3 if it was grilled.

I’m new here and still discovering what great food places resides here in this lovely town. I stumble across this lovely greasy spoon or should I say delicious spoon.
The bison burger here is to die for.

Should be this businesses last stand! Pretty sure they go to wal mart and pick the dogs up off the ground. The chili is bland as hell and it looks like they use government cheese

Love their Chicago Style Hot Dogs!!! Their bread is never soggy and they are always friendly.

Mustards is always consistent and good. Never had a bad dog, burger or fries here. The fries and hand cut, nice and crispy.

Straight up yum. Molto yum. Also great a/​c on hot days.
We always get the basic dog with homemade (real) fries and leave with full bellies.
Go before or after noon — it gets busy.

Mustards simply continues to be the best burger in Boulder and I would put it against any burger in the world. This place needs a few VC rounds and it will crush shake-​shack.

Our friends from town took us here and we got hot dogs and burgers. I got the buffalo burger and it was delicious. I’m a big fan now.

I am such a fan of Mustard’s that my coworkers know a good gift is a certificate to this location.
To be fair, I work around the corner so I am awfully biased. But I also know that I have had so many bad veggie burgers in my lifetime — and thankfully, the good people at Mustard’s have ended this streak. Everything I have had off their veggie-​friendly menu has been spectacular, but the tempeh burger is truly unparalleled.
I endorse their tofu reuben and soy hot dogs with all of my being. Add to that their handcut fries and I am one happy camper.
Adorably, they also offer blankets for those who may be interested in having a picnic by the Boulder Creek. Geez, could this place be any better?
Unfortunately, since the place is so awesome, you have to pick when to go. This location is popular with the Boulder High students during their lunch periods, which makes it nearly impossible at times. Seating is limited, but there’s reasonable turn over during the calmer periods. Take advantage of a spot outside whenever you can because the people watching at Broadway and Arapahoe is pretty priceless.

Tasty combo for $ 7.06. Friendly staff and tasty food. Popular for a quick lunch or while chiilin in Central Park. Guy food mainly.

Coming from Chicago I ordered a single red hot Chicago style and chili cheese fries. What I got was correct. For the first time in Colorado they served the dog on a poppy bun without ketchup. The dog was exactly like what I get at a stand in Chicago. It was coming on $ 5 which is a bit pricey. The chili cheese fries were okay. Nothing special though. However five stars for a authentic Chicago dog

I was finally able to pay a visit to this Mustard’s Last Stand location recently, after looking for something close to the transit center that had good food and beer. I recall there being a similar restaurant with an identical name in my old neighborhood in Florida, and although there was no relation between the two, I had been anxious to try it out for quite some time. Seems like it had been forever since I’d had a Chicago style hot dog.
A friend had mentioned that the fries were a must try, as I believe they’re hand cut and made on the spot, so I went with a Jumbo Char Dog combo with kraut, dill pickle, and deli mustard. I also got to check out a few rounds of Avalanche Amber Style Ale from Breckenridge Brewery, a local brand.
Gotta admit, this was one of those places you wish would open within walking distance to your house — it was really that good! The employees were very friendly, and although it’s small and there’s limited seating, I was able to stuff myself, my food, my beer, and heaps of snowboard gear all into a corner with no problems.
I’ll definitely be back soon. It appears there’s another location within the 2000 block of University Blvd. in Denver.

I ordered the chili cheese dog with hot peppers. It was just okay. My dog was lukewarm and my bun soggy (but I expected that). There was so much chili it was so hard to eat, you can’t even hold the dog properly. A fork and knife were required.
I also ordered the fries. I was excited to try these fries from the reviews, but they were one of the worst fries I’ve ever had. Could it possibly be that I had old fries that have been sitting out for hours? Maybe. We came in about an hour prior to closing, but that is no reason to serve someone sub-​par fries.
Place is a little dirty. All the tables I wanted to sit at all had seeds on them. There was NO ONE in there so there is no excuse not to have clean tables.
I probably will not return if I were to visit Boulder again.

Best fries in Boulder… maybe? A bold statement, but may be true.
Love that you can get a Chicago dog here!
This place is so UN-​Boulder… in a good way.

The first time I went into the place it was beyond amazing! The service and food were just great! The guy with the beard really helped me by explaining the menu in depth. I kinda am a picky eater. He even gave me two redeemable envelopes to be redeemed after New Years! So when I came back today I was beyond excited to see what I won and have some more awesome dogs. Unfortunately an older lady (seemed to be the owner) would not allow me to redeem them both and was VERY RUDE about it. If I have two why wouldn’t you allow it since it did bring me back? I still like this place anf if I happen to want some and she is working, I will choose another place to eat. All of the other staff was amazing!!! What kind of an example are setting for your staff Ms. Owner?

Favorite restaurant!
I don’t see how some reviewer said the fries have no flavor and are boring. That person is just wrong! The fries are excellent! The veggie chili fries are my best friend.
They have tons of vegetarian options, but I’ll always get the veggie dog with everything (Chicago style). They use the BIG veggie dogs too, not those dinky little ones. I usually can’t finish the last bite, it is too much food.
Also, (typical Boulder) the cashiers are always friendly and the service is fast. No complaints at all!
Keep on keepin’ on Mustard’s!

The name always intrigued me but there are so many good restaurants in Boulder and when visiting so little time. I wish I would have tried this hot dog gem sooner. Yes, you have to pay for parking get over it! The next best thing is in Chicago and the last I checked SouthWest is getting $ 290 for the Wanna get away flight. That’s an expensive dog! The Vienna hotdogs were fantastic and the hand cut homemade fries were even better! I will definitely return to this Boulder institution and try the burger next time. I highly recommend trying this spot. My wife said to mention they have tofu dogs and burgers as well.

The fries are flavorless and boring, no salt either. The chilli doesn’t even have meat (What kind of hot dog place doesn’t have chilli meat? Lame) I understand they are trying to make this vegetarian friendly but have a meat chilli option. You have the ground beef for it!
You could get better hotdogs at the grocery store. Save your money. Plus the cashier (typical boulder) didn’t smile at all, such lack of customer service.
Go to Costco for a good hotdog. It’s a fraction of the price and tastes WAY better.
