You won't find a sign advertising this popular South Grand institution. Nestled above Mekong on the corner of Grand Boulevard and Hartford Street, Upstairs is the go-to place for cheap drinks, dancing and local DJs spinning every night of the week. If sweating it out on the dance floor isn't your cup of tea, arrive early to snag a booth to people-watch; you won't be disappointed. If the scene upstairs gets stale, bounce down to uber-mod Barbarella, or the Blue Room, the two sister bars housed in the same building. The Upstairs draws a diverse crowd and is the unpretentious, South side alternative to the St. Louis club scene. There's generally a cover on the weekend, but if you're looking to party on the cheap, weeknights are your best bet.
