"Puertas cerradas, or closed-door restaurants, are a unique Buenos Aires dining experience (think of them like secret supper clubs with home-cooked meals), and we recommend visiting at least one. Treintasillas has been around for more than a decade, and makes you feel like your swanky chef friend invited you over for a romantic dinner in their dreamy courtyard. The fixed, four-course menu changes weekly—yes, beef usually makes an appearance, but vegetables get to be the main character in many of the dishes you’ll try. Treintasillas is only open on Thursday, Friday, and Saturday nights, and you’ll need to make a reservation via WhatsApp, email, Facebook, or Instagram. " - martin chavesta, annie bacher
