Like most modern conflicts, the rivalry between soft and hard tacos will not end until one side gets eaten by a bear. Broker a culinary truce with today's Groupon: for $15, you get $30 worth of Mexican fare at Beto’s Mexican Restaurant.

The culinary caballeros at Beto’s Mexican Restaurant have been plating authentic Mexican tacos, fajitas, and enchiladas for more than 15 years. Dark orange walls encircle spoons as they dive into homemade tortilla soup and emerge brimming with shredded chicken, fresh zucchini, squash, and monterey jack ($5.99). A flat-screen TV flashes real-time updates about the impending vulcanized rubber shortage as diners delve into homemade chili rellenos, the shredded beef and caramelized onions of which nestle in a stuffed poblano pepper fried to a golden brown ($9.99). Waves of mexican rice bearing North Atlantic tilapia fillets ($11.99) roll over the restaurant’s brick floor, and, like a retainer that plays old Sonny and Cher episodes, the Beto Dinner offers taste buds variety, from a tamale and cheese enchilada to a toasted meat taco, soft cheese taco, and guacamole salad ($9.99).
