Irma and her family dish out home-style Mexican specialties to a wait-in-line breakfast and lunch crowd (weekdays only) of lawyers, judges, cube-dwellers, and sports fans. The surroundings may be homey, but this place is not cheap—still, the food has made Irma's a local landmark. There's no menu: your server will tell you what is available. Opt for the chicken-and-spinach enchiladas with green chili sauce, and wash it all down with the famous lemonade. Irma opens on weekends when the Astros are in town—and stays open until 6 pm during the week on home-game days.
