Neat burger joint in Boulder. One of the best burgers we ever had. Good beer selection. Atmosphere was very good and good artwork. Excellent place for college students. Worth going to even if you live in Denver.

The building is cool. The food was very disappointing. Tried all the items featured on Diners Drive Ins and Dives. The fried mac and cheese balls tasted good, but were stil frozen in the center. The cowboy reuben with beef brisket, not good, the meat was old and dry. the pizza was almost inedible, the crust was like cardboard. and i received my side salad after we had finished eating. took 20 minutes to get the bill. never going back there.

Their food is great and is worth the little extra it costs over a normal burger place. But I'm taking off two stars because of how much hassle it is that they screw up more than 2/3rds of the delivery orders I make. They aren't going to start getting it right until we call and complain to force them to waste money sending a driver out for the corrections.

The Sink? Extremely disappointed in how this restaurant opperates as a company. They cater several Fraternity houses in Boulder and appear to dump their left overs on our kids. The houses get spoiled milk, moldy bagels, seriously? Completely inedible. Do not support this company - they do not care about their customer base and provide exceptionally poor service.

Hi Vicki, We appreciate your feedback. The problem with the food was in part, related to equipment issues at the empty house over spring break and, in part, an oversight by our cook. There was a gallon of expired milk and the blueberry bagels displayed some discoloration that was not mold. Upon learning of the issue this morning, 3/31, our Chef Matt met with Daniel and they resolved the issues. We provide our fraternity clients with fresh, restaurant quality, scratch made meals. The guys eat well. Fresh Herb Roasted Chicken with garden vegetables and roasted red potatoes for dinner Sunday, fresh made Beef Bolognese for dinner on Monday and scratch made Chipotle Roasted Pork burritos for dinner tonight. Please come in and be my guest for a meal at The Sink. I would love to give you a tour of our kitchen and show you how we operate. You can reach me at

A good selection of food at a reasonable price. Very cool to eat at such a historic place.

The burger that I had was amazing. It's a very interesting restaurant with lots of nice people. The place is really packet which means it's good but it does take a bit longer to get your order.
