In mid-1968, Christian Guignard opened his first grill restaurant near the Champs-Élysées in Paris where prime rib, served on a thick wooden board with matchstick fries. Without conforming to gastronomical tradition, changes such as vegetarian dishes, Braille menus, and sides of green beans were later added. In February 1992, Group Flo (led by Jean-Paul Bucher) bought the assets of Hippopotamus.
