See our wallet? It's fat and happy, just like us. The most we can spend at this peppy little hole in the wall is $8.50, and that's for a hefty platter of fajitas, grilled steak with green peppers, tomatoes, onions, refried beans, rice and flour tortillas. Just $5.75 gets us a combo of crisp beef picadillo taco, chorizo tostada, and cheese enchilada. We've made entire meals, actually, of the basket of corn chips and mild salsa (free), plus a soft chicken taco stuffed with lots of shredded breast in natural juices, and piles of crispy lettuce and tomato ($2.25). Even if we splurge for a side of fluffy Spanish rice or creamy refrieds, it's just a buck more. We love that it's chic and cheap, too, with Mexico City-style treats like a quesadilla (not the usual gringo affair, but a turnover of corn dough filled with picadillo or chorizo then deep-fried for $2.30). Enchiladas aren't everyday fast food, with zingy tomatillo and Mexican cheese (just $2.30). And the capper: A high-octane margarita is only $2.75.
