The pioneer of molecular cooking spots in Buenos Aires, chef Alejandro Digilio deserves all credit for bringing this style of cooking with foams, gels, and powders to the dining scene in Buenos Aires. Over the last couple of years, however, the restaurant has started to rest on its laurels a bit, with repetitve menus and less attention to detail than in its early days. It's still an eye-opening experience, but one that can now be had at any of a dozen other spots in town, and often a lower price. Still, it's a charming room, impeccable service, and an opportunity to try something different from the pizzerias and steak houses that surround it in San Telmo. No à la carte menu available, just a multi-course tasting menu.
