All games in the RollerCoaster Tycoon series contain shops and stalls. These are used to sell food, drink and souvenirs, and provide facilities such as toilets, first aid and cash withdrawal. They are essential in meeting the guests’ needs and keeping them happy. Most shops generate a small profit.
Shops cannot break down, except in RollerCoaster Tycoon 3.
An overview of all the shops and stalls can be found here.
