A tortilla makes a handy mousepad, an acceptable patch for stiff denim jeans, and, if you draw a face on it, an ideal companion on fishing trips. But there are many other uses for it, as today's Groupon proves: for $7, you get $15 worth of authentic Mexican fare at Caballo Blanco on Franklin Boulevard.

Caballo Blanco's menu is full of hearty Mexican dishes that have been honed over the course of the restaurant's 50 years. Diners can revive hibernating chewing muscles with complimentary flour chips, which, unlike corn chips, arrive in a basket rather than on a cob. Lunch and dinner combos cater to indecisive diners and feature edible groupings such as two cheese enchiladas and one beef taco ($10.95), and the chili colorado synthesizes savory ingredients including cubed beef, chili sauce, rice, and beans in one bowl-style hat ($10.75). Sea-favoring foodies can feast on the shrimp, bell peppers, onions, and tomatoes of the camarones rancheros ($12.95), and all parties can revel in Caballo Blanco’s friendly atmosphere by confidently kazooing along to the dining room's culturally diverse playlist.
