its the only place on this list i set foot in it. Cons: there are much better places. muuuch better. and cheaper. french cuisine is massively overrated if they have the menu in three lang. go elsewhere. maybe to marseille.
Good food at reasonable prices, warm atmosphere. Get a taste of the south-western gastronomy. Note that a second J'Go opened last year in Paris, in St-Germain, it's the third after Toulouse and Drouot
