The Sink

Big fan of the chicken and waffles! I had the portabello mushroom «burger» this time and it was good. A little slippery and could have been improved by seasoning or marinating

Perfect pear and blue cheese salad with grilled salmon! The balsamic dressing was flavorful yet mellow and the salmon was perfectly cooked and flaky. You’ll love this place!

Really cool atmosphere. service was good and fast considering it was a saturday evening. Had the burger with queso on it (dont judge me) and the bacon stuffed jalapeños. I would definitely go back and/​or recommend it to anyone traveling to boulder.

So I loved going to the sink from time to time for a long time, overall decent food. But recently I’ve been ordering through hungrybuffs and the service is bad. Today I got a phone call that they are not allowing any substitutions on speciality pizzas, which is frustrating because it makes the pizza I want (with single substitution) both $ 3 more expensive and eliminates the mixed cheese topping.
On top of that, the menu states clearly «Please limit substitutions on our specialty pies to one item.» But when I place an order with a single substitution I got a call from the restaurant telling me that isn’t possible.
I’ll probably still go by the restaurant from time to time, but I will try to avoid ordering through hungrybuffs.

Just moved to Glendale, it was a 45 minute drive to come here but we will be back! Great food & service. Fun atmosphere. The chicken fingers & fries from the app menu were great and my husband enjoyed the Cowboy Reuben.

All I can say here is this: be prepared to wait. We waited for at least 90 minutes for our food to arrive.

Their burgers are phenominal, and so are the deep fried deviled eggs. We went off of a recommendation from a friend and loved every aspect of our meals. Staff was friendly and the atmosphere is definitely fun, we kept reading all of the murals/​commentary on the walls. But throw a little chipotle aoli on your burger and it takes it to a new level

Went there for lunch after a CU Boulder college visit. Very funky vibe which other Unilocalers commented on. Low ceilings, graffiti everywhere. We had great service, from DDD Texas Onion burger, to Love of Garlic burger. All were great. Strong recommend.

Terrible experiencing ordering from this restaurant through HungryBuffs, I ordered a burger and fries and I asked for EXTRA Ketchup and Hot sauce, i received the standard amount of ketchup and no hot sauce. When I called customer service they offered to have the driver bring me ketchup, but by the time this would happen my food would be cold! Worst experience ever.
Food is decent tho.
Bottom Line:
Good food. Be careful when ordering from these guys if your orders requires extra attention to detail. It sounds to me like they can’t handle it.

The Sink is your classic hole in the wall college town eatery, complete with the failed health inspections. That being said, it is still a must visit when in the area. The walls and ceiling are decorated in signatures and art, more than enough to entertain you throughout your visit. Overall, the ambience is everything you would expect from a college hole in the wall.
The menu features plenty of burgers and pizza. Mac and cheese, salads, sandwiches and a few other items round it out. I went with a Spicy Bacon Bleu Burger and fries. My girlfriend went with some pizza, and we split a mac and cheese side.
Food came out fairly quickly, especially with the large crowd. We were there on a Sunday night, right after a Broncos game. The food was good. Not amazing or life changing, but good. The patty on the burger was better than most, and the toppings tasted fresh as well. The sauces they have were also pretty good. My girlfriend liked her pizza as well. The mac and cheese was a weak point, and some of the fries were a little cold, but overall it was a solid meal.
I’m not sure when the next time will be that were back in Boulder, but I will likely stop by here again.

Awesome location and ambiance!
The sink perfectly captures the college culture of CU Boulder. The walls and ceilings are decorated with artistic graffiti and photos that provide a laid back and casual vibe.
The menu reflects a wide variety of burgers, pasta dishes, and pizzas. Highly recommend the Mac and cheese with buffalo chicken, the POTUS pizza, and any of the burgers!
The sorority girl cocktail is also apparently a big hit :)

Note the remnants of the meal devoured. Note the party drunk beer (2^nd).
This is my lunch place and my «I’m bored» place.
This is my place.
Eat here. Drink here. Love here.

I loved this place. It reminded me of something I would find back home in New Orleans. Low ceilings that you can tag and artwork drawn on the walls gave this place a unique vibe. I got the sink sliders that were so yummy! But the pizza at the table next to me looked just as good. I’ll definitely be back!

I absolutely love this place. It looks like a strange little hole in the wall, with low ceilings and graffiti on the walls.
Then you really get to know the place and it gets better every time you go. The low ceilings add character. What I once thought of as «graffiti», I now see as amazing, creative, and hilarious artwork!
The drinks are crazy good. The pizza is amazing! I would eat there every day of I lived close.

Had the Texas onion straw (DDD) with fries. Good flavor, flaky bun. Good jalapeño taste. Meat cooked to order. Not too spicy. Fries ok. Condiments like the sliced pickles were very good. Nice purple onion and tomatoes.
Garlic burger pepper crusted top with onion straws and spinach. Really enjoyed. I left the bun off and they wrapped it in nice lettuce leaves. Great side salad with ranch.
Did the 3^rd kingdom ipa which may have not been chilled enough but decent taste. Ice tea brewed.
Josephine did really nice job. Got sample of beers before ordering. Kept water full. Cool vibe here.

A MUST if you are in boulder. The space alone is so cool with paintings on the wall. The history is awesome too!
Happy hour deals rocked and we were able to eat and grab a drink for under $ 30. Wings, jalapeños and fries rocked!
The only complaint would be the service. Our food came out a bit later than we would have expected especially since they weren’t really that busy. The waitress was very friendly though.

Went back for a re trial. Nate and Jordan were taking care of me and my friend. I had the sink burger with jalapenos and the spicy jack cheese and it kicked my taste buds into the «hot» zone for sure. My friend had the Brewers burger and confirmed my past review, its awesome. We had their beer special which was a heffeweisen and rolled off after lunch to go do stuff.
Good service from a classic establishment. Ill be back and I’ll bring my friends too!

Love this place. Eat here all the time and always bring out of towers. Cool environment and of course we’ve all signed the wall.
That being said the prices aren’t bad. The portions are huge and they have tons of options for vegetarians and The GF set. My faves are the spicy black bean burger and the buffalo tofu sandwich.

Yeah, I’m giving this Boulder institution two stars. While I enjoyed all the wall murals and ceiling scribbles, the food was pretty mediocre.
My table shared a plate of fairly unremarkable nachos. It’s been a while since my college days, but I don’t think my standards for nacho plates have changed *that* much.
The other big annoyance for me are the ceilings. The main dining area’s ceilings are just a little over 6′ tall (and I’m a lot over 6′ tall), meaning I had to duck in to and out of the restaurant.
While I know there’s not a lot you can do to control for this, it’s the sort of thing that would make me consider eating some place else if I’m back around The Hill anytime soon.

The sink never disappoints, whether you come to drink and have a social night out for a quick bite to eat everything is always delicious.
They recently changed their menu and added a ton of different and new items. New and noteworthy items include the Mac and cheese, they have a few different types that you can get but the buffalo Mac is pretty fantastic! Another one of my personal favorites is the herbie combination, a burger Fries and a salad all for a great price.
Drinking here is always a great time! A friendly tip is to order the strawberry kamikazee shot, it has strawberry purée added into it and it’s so delicious you’ll want to make it a drink!
