The Sink

History and Atmosphere

Established in 1923, The Sink stands as Boulder's oldest continuously operating restaurant, evolving from a burger joint to a beloved campus staple near the University of Colorado. Its interior captivates with low ceilings and walls entirely covered in colorful, comic-strip-style murals painted by artists, students, and patrons over decades—dragons, superheroes, aliens, and quirky scenes create an immersive, lively backdrop that feels like stepping into a living art gallery. The vibe is casual and energetic, drawing crowds for its unpretentious charm and role as a social hub.

Signature Menu Highlights

The menu centers on crowd-pleasers like the famous Sinkburger, a six-ounce grass-fed beef patty hailed as Boulder's best by locals, customizable and charbroiled to perfection. Wood-fired 'Ugly Crust' pizzas offer bold toppings such as the Buddha Basil Pie with tofu and spinach or customizable combos blending smoky crust with fresh ingredients. Standouts include the Cowboy Reuben—tender, 10-hour smoked brisket with super slaw, cheddar, and chipotle BBQ on rye—and creamy mac & cheese variations like buffalo or bacon-loaded. Appetizers shine with loaded nachos piled high with cheese, jalapeños, olives, and tomatoes, plus bacon-stuffed jalapeños and Creole fries seasoned southern-style.

Drinks and Sides

A solid selection of local Colorado beers and ciders complements the food, making it ideal for game-watching or casual hangs. Sides like sweet potato fries, cajun fries, and complimentary Elephant Ears—cinnamon-sugar pizza dough bites—add sweet-savory flair. Portions are generous, emphasizing hearty, no-fuss pub grub suited to Boulder’s active crowd.

Service and Practicalities

Service is typically friendly and efficient, with quick seating and food delivery even during peaks, though it can get loud with music and chatter—opt for outdoor patio when available. Open daily from 11 AM to 10 PM, it accommodates walk-ins well, with moderate pricing reflecting its institutional status. Clean restrooms and QR menus enhance the experience.

Beyond food, The Sink's draw lies in its celebrity lore—from Barack Obama to Anthony Bourdain—and Food Network features, cementing its status as a must for Boulder newcomers. It's where history meets hangout, offering reliable comfort food in a uniquely painted space that sparks stories and photos.
