Ever since Arizona and Mexico became neighbors last year, Phoenix residents have sought out the mythical hidden restaurant that fuses the two cultures' cuisines together. End the search with today's Groupon: for $3, you get $10 worth of Mexican-southwestern fusion cuisine and drinks at Fuego Tacos on East Camelback Rd.

Fuego Tacos' menu is full of award-winning mojitos and tacos bearing slow-roasted meats, unexpected toppings, and local flavors. All tacos are wrapped in locally made corn tortillas, sprinkled with sugar-cured cabbage, house-made pico de gallo, and a house blend of oaxacan cheeses, then sided with house-made chips and salsa, arroz gondulas, and Cuban black beans. The short-rib barbacoa ($10) tops Angus short ribs braised in a liquid base of pineapple, soy sauce, chipotle, and Dr. Pepper with a layer of pineapple-habanero hot sauce. Culinary pedestrians can take a walk down chicken street ($9), where garlic cloves, rosemary, and citrus juices saturate thigh meat. Spicy vegetarian ($9) spicies up a flora medley of guacamole, peppers, onions, black beans, corn, and pico de gallo with a savory tomatillo verde salsa, and houses it underneath a crunchy corn-tortilla roof.
