Coffee shops, cafes, coffee bars, and espresso bars, are retail business establishments that specialize in serving coffee and espresso drinks, often providing a dining area with free wifi and a variety of seating options. The layout of a coffee shop will most often be determined by the available square footage of the shop space, which can range in size from kiosks of less than 400 sq. feet to an indoor space upwards of 1000 sq. feet that could comfortably support more than 50 guests at a time. Fixtures such as coffeemakers, espresso machines, grinders, refrigerators, and ice machines, along with storage accommodations and ample counter space are all vital to the functionality of a coffee shop.
