Starbucks is a national chain of gourmet cafes, which caters to coffee-drinkers. Many of their customers commute from the suburbs, and several of the stores are located in business districts so they may better accommodate the commuters' needs. Starbucks sells their private brand of coffees, and also accompanied them with fresh baked goods. They have a synergy between their stores and their website, both of which help to maintain an advantage over competing local coffee shops. This is a description of Starbucks:
