Adding salsa to a dish does not make it Mexican, just as adding novelty sheriff's badges to your shirt does not make jaywalking legal. Patiently wait to cross culinary borders with today's Groupon: for $20, you get $40 worth of authentic Mexican cuisine and drinks at Los Antojos in Chula Vista.

Los Antojos' professional salsa senseis artfully plate an extensive menu of authentic Mexican cuisine. Mouths can plummet into an appetizer of ceviche Los Antojos, which flaunts ahi tuna, octopus, and scallops accessorized with fresh avocado, mango, nectarine, and strawberries swiped from Carmen Miranda's hat ($11.95). Chefs bundle carne asada tacos with guacamole, salsa, onions, and cilantro ($3.95), and they marinate ox tails in dark beer before introducing the tender morsels to sides of rice and beans ($6.96). The seafood selection includes shrimp with tamarind sauce ($17.95) and pescado en salsa de frijol negro, a white fish filet topped with black beans and swirled in dark beer sauce (15.95). Beer and wine cool throats riled from contentious debates over flour versus corn tortillas, as barkeeps craft cocktails such as mango margaritas ($5.55).
