Mr Smoothie, Gaithersburg

On a hot summer day, the interior of Mr. Smoothie & Frozen Yogurt Bar looks a bit like paradise. Staff members man blenders whirring together non-fat yogurt and a choice of two fresh fruits into their signature smoothies, allowing customers to cool off with treats that are refreshing, healthy, and able to put out a very small fire. Everything made at Mr. Smoothie is customizable, and guests can opt to pare down the sweetness by only drinking freshly squeezed juice or creating fruity freezes from the same juices blended with chunks of real fruit. Eleven flavors of coffees are used to make frappes, with skinnier versions available for those desiring less calories and more protein. In fact, staff members can add a range of supplements and boosts to any smoothie or drink, adding ingredients that build muscle or nutrients that aim to improve hangovers.
