Not historically residential, Downtown has recently experienced a revival of its restaurant and arts scenes in ways that have prompted young professionals to move in en masse. You’ll find them in the area’s pedestrian-friendly Market Square district, or hitting up the bars that surround the sports stadiums in EaDo (East Downtown). During the workday, oil-biz types and bankers mingle in the tunnels, a subterranean network of air-conditioned walkways connecting several office buildings. On weekends, an older, more distinguished crowd treasure hunts at the Discovery Green flea market or takes in shows at the city’s Theater District.
