Underground Hall is a food hall and late-night dining destination in downtown Houston at Prairie Street and Main Street, situated next to The Moonshiners Southern Table & Bar. While not a speakeasy in the traditional Prohibition-era sense, it serves as a multi-vendor food and beverage hall with various dining and late-night options. Operating hours are Monday through Thursday 11 a.m. to 11 p.m., Friday and Saturday 11 a.m. to 1 a.m., and Sunday 11 a.m. to 9 p.m. The space offers diverse food and drink options from multiple vendors, making it a destination for those seeking variety in a downtown location. If you're looking for actual hidden speakeasy bars with secretive atmospheres, Houston has many other authentic options, but Underground Hall offers a different kind of underground experience focused on inclusive food and beverage options.
