The Sink: A Boulder Classic That’s Still Crushing It
If there’s one place on The Hill that captures Boulder’s spirit better than almost anywhere else, it’s The Sink.
This legendary spot has been around since 1923 (yep, more than 100 years!) and has grown from a small neighborhood eatery into one of the most iconic restaurants in Boulder. The walls and tables are covered with art and images that are a window into Boulder’s unique history. Generations of CU students, locals, and even celebrities have left their mark—literally. The ceilings are covered in colorful graffiti and signatures from visitors over the decades.
Why The Sink Is Special
The Sink isn’t just a restaurant—it’s a tradition. Ask anyone who went to CU, and chances are they’ll have a story about it.
It’s also been the backdrop for some pretty fun claims to fame:
● Guy Fieri’s Diners, Drive-Ins, and Dives featured it on Food Network
● Presidents, rock stars, and pro athletes have stopped by for a bite
● And CU students, of course, LOVE IT
Our Take
When we end our walking tours at The Sink, it’s not just for the food—it’s because The Sink is part of the real CU Boulder experience. It’s the kind of place where you can picture yourself celebrating a Buffs win, grabbing lunch with friends, or bringing your family to soak in the Boulder vibe.
