Houston for a week
we found Cava Bistro, mediocre. Original Mama Ninfas, very good. El Rey Taquiria, very good. Mi Luna tapa, the best of all. Not the best tapa you'll ever have, but very good.
Sambuca, a small national chain, mediocre. Falafel Frenzy or Prarie, very good food, very slow at lunch. Corner Bakery Cafe, mediocre. Cabo, feh!.
Churrasco's is a Houston institution - there's a location on the corner of Shepherd and Westheimer that's not too far from downtown. The chef/owner also has a fabulous place downtown in the Hobby Center - Artista.
There are wonderful "dive" Latin American places to eat as well. My favorite is Mi Pueblito (Colombian food) on Fondren just off Richmond.
