The Dinner Detective eschews campy costumes and plots for an exciting evening of food-accompanied mystery and paranoia, where actors hide among the diners as they play innocent and make everyone a potential suspect. To solve the crime, guests freely interrogate one another, chivvying out clues about the murderer and determining who has a bloodthirsty look in their eyes. Between dramatic deaths and simulated police involvement, guests dig into four-course meals, washed down with bottomless iced tea and drinks from the cash bar. The diner who comes closest to solving the mystery through their snooping goes home with a prize basket to show off to their friends or split with the murderer as per their shadowy conspiracy.
