I think it's terrific. My faves are the braised pork burrito and the pork or poblano tortas. Steak and chicken burritos and chicken torta also very good. As far as I'm concerned the taco/burrito axis now runs from Villa Mexico to Olecito to Tacos Lupita.
liked it in May, like it now. since then have tried the shrimp taco and the chile taco, approved of both. btw, don't make the mistake of over-ordering based on small price--they're a lot of food for the $.
