This “café” or cafeteria is sharing the esplanade between the monumental columns with the Tokyo Eat, the restaurant of the Palais de Tokyo (space dedicated to the “avant-garde” art).
It’s cheaper, simple but good, with a “plat du jour” (dish of the day) at 9,90 euros, and a coffea at 2,10 euros. You’ll enjoy the sun and a (little) view on the Seine and the Eiffeil Tower, after your visit of the Musée d’Art Moderne and a look in the book shop of the Museum.
