[from SF fandom] A mass expedition to an oriental restaurant, esp. one where food is served family-style and shared. There is a common heuristic about the amount of food to order, expressed as “Get N - 1 entrees”; the value of N, which is the number of people in the group, can be inferred from context (see N). See oriental food, ravs, stir-fried random.
