Reviews Summary

The Sink is celebrated for its unique, art-filled atmosphere and iconic burgers, with many highlighting its history and quirky charm. While the food is often praised, some diners find the value or execution to be average, and service speed can occasionally be a concern. Despite mixed reviews on some dishes, its status as a Boulder institution makes it a must-visit for many.

"Super cool place. Drove in from Colorado Springs. The place has drawing and stuff all over the walls and ceiling. Also has alot of history. Only had one dish and it is one of the best I had anywhere. It was mac and cheese with tempura Cauliflower on top. Never say that anywhere else and never would of thought to try. Great visit, will go again."

No Boulder bar carries its history as gracefully as the Sink, a 90-year-old icon in the University Hill neighbourhood, and a reminder for thousands of their time as students at the University of Colorado. It also might hold memories for Barack Obama and Robert Redford: the president visited the bar in 2012 and ordered a pizza, now designated the Potus pie; the actor pushed a mop as a Sink janitor in his early years. A low ceiling covered with intricate illustrations contributes to the restaurant's intimate, eccentric atmosphere.1165 13th Street, +1 303 444 7465, thesink.com.

Some of the more famous names on the wall include a former president and a guy who makes something called “donkey sauce.” You can also head over to Half Fast, which might technically not be a bar but does serve sandwiches along with pitchers of Strong Island Iced Teas, so technically I don’t care.
