The Sink's Famous Ugly Crust Pizza

The Sink's Famous Ugly Crust Pizza

For decades, the Sink was known to have the best burger in Boulder, so it was time to step up our ‘za game. In this case, “Ugly” is a term of endearment used to describe the big, thick, floppy crust that borders a Sink pizza. We still think you’re beautiful, Ugly Crust Pizza.
