The Flat Houston blends a Montrose cocktail lounge with a low-key dance floor, moving from relaxed patio drinks into DJ-led house, hip-hop, funk, and global grooves. The converted house keeps the night intimate, and regulars come as much for the music selection as the bar. It works best for a small group that wants to talk first, dance later, and avoid the production of a giant nightclub. That final detail gives The Flat Houston real staying power.
