A progressive dinner (US) or safari supper (UK) is a dinner party with successive courses prepared and eaten at the residences of different hosts. Usually this involves the consumption of one course at each location. Involving travel, it is a variant on a potluck dinner and is sometimes known as a round-robin. An alternative is to have each course at a different dining area within a single large establishment. In a safari supper, the destination of the next course is generally unknown by the participants, and they have to decipher a clue before moving on. In the USA, participants go to each house for the various courses. Often there is a regional theme for each dinner, such as Italian, German, or French. Various wines to suit the courses are often served at each location. A challenge is keeping the food warm and ready at each location. An alternative is to have the courses at different restaurants.
This style of eating has recently become popular as a charity fundraiser in rural Britain and is seen as a good way of meeting different neighbors in the community by virtue of each participant having separate guests.
Safari supper can also be used to describe a type of baked curry consisting of ground beef and rice in a spicy-sweet sauce.1
