Located inside the Old Boatstore Café in Cornwall, England, in an appointment only corridor, there’s a blue, seemingly normal display case tacked to the wall.

Upon closer inspection, one can see various food articles like crusts of bread, sugar packets, chickpeas, and coffee-stained napkins sheltered under little glass domes, all leftover from the plates of celebrities who have dined at the café. The actress, Mia Wasikowska, for example, has a courgette from her soup on display, while Prince Charles has some bread pudding he chose to leave unfinished.

The café has an open and community-minded atmosphere, priding itself on vegetarian food and locally-sourced seafood, but one must arrange a private tour to view this semi-masticated celebrity collection.
