To create the ultimate hot bean juice, Bruegger's has teamed up with Green Mountain Coffee, which deftly wields the double-edged sword of rich, flavorful coffee and socially responsible fair-trade practices. Bruegger's coffee menu offers a slurpable rainbow of classic brews and unusual, globetrotting options ($1.59 for a small). Relish region-specific flavors and aromas from the misty hilltops of Tanzania, the lush farms of Mexico, or the turbulent moons of Endor. Membership in the Bottomless Mug Club also ensures free refills of steamy chai tea and hot chocolate (both $1.79 for a small), soft drinks ($1.59 for a small), and an assortment of hot teas ($1.39 for a small) for java-less jaunts. Although today's Groupon does not cover food, Bruegger's offers delectable deli eats to pair with your bottomless beverages, including kettle-boiled bagels, breakfast sandwiches, and lunch fare.
