A tortilla makes a handy mouse pad, 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 $10, you get $20 worth of Mexican fare and drinks at Barberitos on Agerton Lane.

Barberitos assuages stubborn hunger pangs with a zesty mixture of fresh, made-to-order southwestern fare. A popular option on the diverse menu, the Heavy D burritotests tortilla strength with portions of rice, beans, meat, cheese, salsa, guacamole, sour cream, and lettuce ($6.79). Because meals, like pacemakers, can be fun to put together yourself, Barberitos serves sizzling fajitas, a platter of meat, three taco shells, and tasty toppings ready for assembly ($8.99–$9.99). On Fridays only, jerk fish tacos prove they're actually quite nice with a medley of grilled tilapia, cheese, guac, cilantro, and lime ($3.59). Meat dodgers can indulge in vegetarian options such as the vegetarian quesadilla, a grilled 10-inch tortilla filled with cheese and beans or a choice of vegetables ($5.39).

Festive colors accent the cantina's interior, matching the zest of the culinary treats. Diners can use the free wireless internet to check the standings of their beloved local team or the stock price of their beloved local conglomerate.
