A fruit smoothie is the perfect pick-me-up while strolling through the streets of downtown San Francisco. The Jamba Juice on New Montgomery Street in the South of Market (SoMa) district is a great stop for a smoothie and a snack. This juice bar, which began only serving smoothies, has expanded over the years to offering small bites, tasty flatbreads, cold-cut sandwiches, and hot breakfast wraps. Jamba Juice offers one free boost to their customers. These boost additions contain different combinations of vitamins and nutrients to help revitalize the body. With an added energy or immunity boost, patrons of SoMa’s Jamba Juice will have the vitality to explore the rest of the city.
