By exchanging food, neighbors define their relationships: good neighbors lend cups of sugar, friendly neighbors give pies, and bad neighbors spoil barbecues with vindictive rain dances. Enjoy the friendly exchange of the cuisine-next-door with today’s Groupon: for $7, you get $15 worth of tacos, enchiladas, and fajitas at Dos Juans Puffy Tacos.

Dos Juans dishes up savory skillets of authentic Mexican fare and signature puffy tacos in a casual BYOB restaurant. The menu delights diners with inventive tacos, such as the tacos Diablo ($8.99), fresh shells stuffed with spicy pork and anchos chilis hot enough to melt the icicles off eyebrows. Chimango tacos ($8.99) sweeten the scene with slow-cooked pork, mangos, and garlic, and signature puffy tacos beef up ordinary shells with a delightfully soft exterior. On weekends, brunch dishes deliver generous portions of classics, including breakfast burritos ($6.99), the perfect follow-up to a night on the town or a dawn on the high seas.
