A theme restaurant is a type of restaurant that uses theming to attract diners by creating a memorable experience. Theme restaurants have a unifying or dominant subject or concept, and utilize architecture, decor, special effects, and other techniques, often to create exotic environments that are not normally associated with dining because they are inaccessible, no longer exist, are fictional or supernatural, or taboo. The theme may be further extended through the naming and choices of food, though food is usually secondary to entertaining guests.

A restaurant is a business that prepares and serves food and drinks to customers. Meals are generally served and eaten on the premises, but many restaurants also offer take-out and food delivery services. Restaurants vary greatly in appearance and offerings, including a wide variety of cuisines and service models ranging from inexpensive fast-food restaurants and cafeterias to mid-priced family restaurants, to high-priced luxury establishments.
