I've been to a lot of Mexican restaurants, and Luchitas is one of my favorite. The food is always fast, flavorful and reasonably priced. Some of my favorite dishes are the pollo tinga, the tacos Mexicanos and the flautas. It's hard to find a restaurant in this category that can deliver such fast service while maintaining fresh, quality ingredients. Luchitas does it.
As for seating, I'd recommend the bar - which has several large, flat-screened TVs perfect for watching games - or the patio, which is a casual, sun-drenched area.
Lastly, I have to mention that the skinny margaritas are the best.
