"Open for: Lunch and dinnerPrice range: $$Chef Bertrand Grébaut’s seafood bar is perennially one of the hottest places in Paris, and it’s especially hard to get a table since the restaurant doesn’t take reservations. The menu changes daily, but offers dishes like smoked shrimp with roasted red pepper and white beans, tuna tartare, ceviche, oysters, crab fritters, and more. It also boasts terrific platters of raw seafood like clams, shrimp, sea snails, and other delights. Located in the 11th arrondissement.Know before you go: If you want to beat the line, try to go right when it opens, at 7 p.m., or late, after 10 p.m." - Alexander Lobrano
