This small upscale bistro serves downtown lunch-goers and Astros fans from a short and ever-changing Tex-Mex and southwestern menu. Irma's is open for all Astros home games Mondays through Saturdays, but is closed for Sunday games. The doors open three hours before first pitch.

While you're there, make sure to listen closely because there are no printed menus. Instead, servers recite the day's offerings to diners, ranging from $10 to $25.
