Before tacos were used in Mexican cooking, they were used to teach children how to tell the difference between hard and soft cover books. Enjoy the taco in its tastiest role with today's Groupon: for $7, you get $15 worth of Mexican fare, margaritas, and beer at Taco Joint in Lincoln Park.

The cuisine team at Taco Joint distributes menus depicting authentic Mexican tacos and street fare inside walls depicting colorful murals. The barbacoa, a culinary tradition of central Mexico and the northern parts of Poland, satiates beef cravings with braised brisket and flavorfies dinner-demolishing devices with cilantro, onion, and roasted jalapeno salsa ($3). The ceviche taco abbreviates hunger pains with a bonanza of citrus-cured tilapia, tomato, cilantro, red onion, roasted red pepper, orange, and avocado over a crispy tortilla floor ($2). Stomachs in want of sustenance can also obtain south-of-the-border succor with Mexican-street-fare-inspired hongos huaraches, a flatbread dish speckled with sauteed mushrooms and roasted corn ($5).

Guests can quash liquid longings by sipping specialty margaritas— concocted with more than 50 Blue Agave tequilas— such as the Zocalo margarita, which unites Lunazul Blanco tequila with triple sec and lime juice ($7).
