The Sink Inside


The Sink was originally a European-style restaurant named Summer’s Sunken Gardens. Its focal point was a large, sunken fountain in the middle of the dining room. To its patrons, the restaurant was fondly nick-named “The Sink”. After purchasing Summer’s Sunken Garden, CU alum Joe Pudlick officially changes the name and runs The Sink from 1940-1954.

The Sink would change hands again in 1954 when business partners Joe Beimford and Floyd Marks purchased the restaurant. By the time Joe Beimford sold his shares to Floyd Marks a year later, the food had disappeared altogether. Marks brought in his son-in-law, Herb Kauvar, in 1958 and the two introduced the now famous Sinkburger (Boulders Best Burger) and its signature Sink Hickory Sauce. Our most famous employee, Robert Redford, was a janitor at The Sink in 1955. Herb and his sons kept The Sink in the family for the next 34 years.

In 1992, the legacy was passed on to another family when the Heinritz’s purchased The Sink. Brothers Mark, Chris and James invested heavily in the careful upgrade and restoration of The Sink. They also introduced Ugly Crust Pizza and the famed Buddah Basil Pie. The Sink also supports the growing craft beer movement by serving local and emerging micro brews.

In the summer of 1995, The Sink went through yet another facelift, which brought the addition of 18 draft beer lines and an upgraded kitchen.

In 2006, The Sink committed to being green by running on 100% wind power. Other efforts include: composting, low-flow water fixtures and energy efficient light bulbs. Results are 30% reduction in water usage and a nearly 10% drop in energy usage.

The “world-famous” aspect of The Sink grew in 2012 with a feature on The Food Network’s “Diners, Drive-Ins and Dives,” and two surprise visits from President Barak H. Obama. In April 2013, Anthony Bourdain and Eric Ripert, reminiscent of The Sink’s Angel/Devil, will bring their “Good vs. Evil” tour VIP party to The Sink.

In 2013, The Sink turned 90 years old. We are proud to celebrate all the tradition, memories, patrons and employees that have made The Sink an institution in the Boulder community.
