Don's Club Tavern is the dive bar that makes other dive bars jealous. This Capitol Hill institution has been serving cheap drinks and zero pretense since 1947, and the vibe hasn't changed much. Think vinyl booths, neon beer signs, and bartenders who remember your order after two visits. The crowd skews local and loyal - neighborhood regulars mix with service industry folks unwinding after shifts. Pool table games get competitive but friendly. Drinks are strong, prices are right, and the jukebox actually has good stuff. It's the kind of place where you planned to have one beer and somehow close the place down. Perfect for when you want authentic Denver grit without the tourist markup. Cash only, obviously.
