History and Atmosphere

Established in 1923 and renamed The Sink in 1940, this Boulder institution has evolved into a vibrant hub on The Hill near the University of Colorado. Low ceilings and walls covered in comic-style murals of dragons, aliens, superheroes, and local art create an immersive, quirky environment that feels alive with history and creativity. Patrons have contributed to the decor over decades, making every corner a visual feast. The casual, hip vibe draws crowds for its laid-back energy, blending college-town spirit with timeless appeal.

Signature Dishes

The Sinkburger, a six-ounce grass-fed beef patty named Boulder's best by local publications, anchors the menu alongside customizable wood-fired Ugly Crust pizzas with bold toppings like buffalo mac and cheese or Buddha Basil Pie featuring tofu and spinach. Standouts include the Cowboy Reuben with slow-smoked brisket, super slaw, cheddar, and chipotle BBQ on rye; bacon-stuffed jalapeños; and creamy nachos piled high with cheese, tomatoes, jalapeños, and olives. Sides like Creole fries add southern spice, while desserts such as Elephant Ears—cinnamon-sugar pizza dough bites—satisfy sweet cravings.

Menu Variety and Drinks

American comfort food dominates with hamburgers, pizzas, reubens, mac and cheese, wings, salads, and grilled salmon sandwiches. Options cater to diverse tastes, from spicy garlic lime wings to veggie-friendly pies. A strong selection of local beers, ciders, and espresso complements meals. The moderate price level offers value in generous portions, though some note premium Boulder pricing.
