Soda fountain

Today, a soda fountain refers to the carbonated drink dispensers found in fast food restaurants. These devices combine syrup (commonly dispensed from a Bag-In-Box), carbon dioxide, and water to make soft drinks.

Historically, a soda fountain referred to the part of a drugstore where sodas, ice cream, sundaes, hot beverages, iced beverages, baked goods, and light meals were prepared and served.
