Restaurants are also using the environment to enhance the authenticity of food, explains Spence, so Italian food will taste better if Pavarotti is playing in the background. Many pop-ups now take this idea and run with it, with actors and scenery and a whole story woven around the nationality of the food. Travelling pop-up Gingerline plays on this idea. Its current event, called The Hideout, is secret, but previous events have married food to a theme, including HMS Gingerline, where seafood platters were served in an aquatic setting with sea-shanty sounds, porthole film installations and fake sailor-style tattoos.
