This is another El Tiempo incarnation, so it could be listed in "Places To Eat," but I find the place best suited for margaritas and parties. (Get as loud as you want.) Yes, the tenderloin fajitas are super, but the margarita's are legendary.
This location, once La Jaliescience, a local taqueria with quite a history, is the third El Tiempo after the Richmond and Washington Avenue locations. Although I have spent plenty a night at the original on Richmond, I think this is my favorite.
The bar is the most comfortable of the three. The patios (one in rear and one in front) are a bit small, but the casual midtown locals don't seem to mind. The actual dining room is separated from the bar for a quieter meal. (But who goes for Tex-Mex looking for quiet?) The food is consistently good and, honestly, some of the highest quality Tex-Mex available.
The service on my two visits (once on a weeknight and once on a weekend) has been very friendly and attentive. The restrooms were clean (amazing, actually, if you ever saw the old place) although employees screaming on their cell phones is a major turn off.
Priced a bit higher than most Tex-Mex in Houston, the quality ingredients and upscale environment are worth the extra expense. Call your friends, get there early (it gets crowded) and find an excuse to cut loose.
