A burrito corrals all the elements of a meal into one delicious wrap, just as the periodic table corrals all the elements of nature into one delicious chart. Enjoy this naturally delicious synthesis with today's Groupon: for $15, you get $30 worth of Mexican fare at José's Mexican Restaurant in Cambridge.

Guests to José's are welcomed by owner Carlos Mendez's family, as his mother, father, brothers, cousins, and nephews all work tirelessly to keep the fare fresh and flavorful and the atmosphere friendly. The menu sizzles with homemade south-of-the-border recipes culled from the family's roots in the Mexican town of Tonatico. Slow-cooked pork loin and achiote chili melt into each other's embrace in the cochinita pibil, a traditional Yucatan dish made from Mendez's mother's recipe ($16.95), and Dona Reyna's chili relleno borrows the cook's moniker as well as her insistence that even the veggies eat their veggies, as she stuffs poblano peppers, deep fries them, and serves them with salsa verde ($13.95–$15.95). Chicken sizzles inside the Mexican Flag enchiladas, each one coated in a choice of salsa bandera, melted cheese, or salsa verde ($12.95). Mole-poblano, mole-verde, and mole-almendrado sauces join forces to drench the trio de enmoladas' chicken- or beef-stuffed tortillas in a torrent of smoky flavor ($16.95), and enormous gulf shrimp dance a savory sauté with green olives and wine in the camarones a la veracruzana, enticing tongues to salsa-spattering mambos ($16.95).

Inside the welcoming dining room, vibrant yellow and red walls hold up an eclectic collection of artwork and fiesta-ready flare, providing a feast for hungry eyes. Benches and tall barstools cozy up to warm-red tables as potted cacti in vibrant vessels turn up their needles whenever a passing waiter offers them more water.
