Patrons wander underground into a dark, slightly spooky cavern, or they can stay upstairs and converse with friends on red vinyl couches. Legend has it this place was a tunnel where 19th-century Portlanders were shanghaied, so dim Oriental lights, dragon murals and dive-bar elements lend appropriate atmosphere. It's a favorite among service-industry types, musicians, and the occasional rock star who pops in after a big show. Potent drinks keep the regulars and visitors bubbly.
