A series of small rooms, lounges, and alcoves, each with a different vibe, is what characterizes Le Chacha, a restaurant, bar, and club just a stone’s throw away from the Louvre. The vintage décor and ’30s influences make for a cozy, plush setting. The restaurant, which serves sophisticated French cuisine, revolves around a magnificent grand piano and turns into a trendy bar and club at night. Here, DJs spin electro-pop and entertain the coolest customers until the sun comes up.
