The Bitter Bar is a modern speakeasy located at 835 Walnut St in downtown Boulder, Colorado, distinguished by its hidden back entrance marked only by a single glowing blue light and retractable doorknob with a discrete "bb" smiley face logo. During daylight hours, the space transforms into Happy Noodle House before transitioning into The Bitter Bar at night, creating a unique dual-identity venue. The bar specializes in craft cocktails made with passion over pretense, operated by James Lee, considered one of the nation's finest bartenders, with signature drinks including the Tin Man—a bourbon-based cocktail with elderflower liqueur, lemon, and ginger. Open Tuesday-Thursday 5 PM-midnight and Friday-Saturday 5 PM-1 AM, The Bitter Bar represents Colorado's premier cocktail destination, attracting those seeking sophisticated libations crafted by masters of the craft in an atmosphere of understated elegance.
