This Paris cafe will mail your letter to yourself, even 20 years from now: Inside Cafe Pli
Cafe Pli has been described as Europe’s first dedicated letter café, combining the ritual of a traditional Parisian coffee house with a novel twist on postal nostalgia. Visitors choose a postcard, settle in with a drink from the menu, and write either to their own future self or to someone else entirely, with the option of having the message delivered up to twenty years later.
