SnS comes through again. My wife and I were in Houston yesterday staying with some friends in the Westheimer and Montrose area, and we needed to grab something before we headed out for the evening. I remembered this recommendation (well, I remembered that people had recommended a po-boy shop around there, UrbanSpoon remembered the rest), so we headed over there. It was great! My wife had the oyster and shrimp po-boy and loved it. Because it was Friday and one of the the cooks is from Puebla (!), they were fixing chiles rellenos, so I went unconventional and had that. It wasn't a poblano pepper, but it was stuffed with chopped steak and poblano pieces, and it was pretty good; the tomato sauce was really good. They also make a steak-and-poblano po-boy that looks pretty good; I'll try that next time.
Anyway, thanks to the folks who pointed this place out, and here's another thumb's up.
