It's believed that Ninfa's on Navigation didn't actually become a popular spot until a city councilman once ate lunch here and declared it the best lunch for the Downtown crowd. More than 40 years have passed since then, but the Tex-Mex institution, where Mama Ninfa Laurenzo once made fajitas famous, still rages on as the best lunch spot in Houston. Wander in on a Friday at noon and the dining room is likely to be packed with a line out the door of office workers, families, ladies who lunch and even famous Houstonians clamoring for a table. Stick with the old standby, the glorious wood-fired fajita (skirt steak) or check out chef Alex Padilla's newer, progressive dishes including the incredible queso asado (grilled cheese), octopus tacos or the beautiful whole red snapper. Either way, don't forget to sneak in a margarita on the rocks before heading back to work.
