Maybe it’s the lack of heat: La Boca is beautiful, and expensive, and charismatic, but it is also very bad. I ate there on three occasions, marvelling each time at the gulf between the appealing scene in the dining room, which offers live music at dinnertime and floods of sunlight during lunch, and the astonishing insipidity of what was on my plate. Virtually every dish was a disappointment, sometimes disconcertingly so. Empanadas, an essential avatar of Argentinean cuisine, arrive filled either with bland, greasy ground beef studded with slippery hunks of hard-boiled eggs, or with an oregano-infused Vermont cheddar that congeals almost immediately into a waxy blob. Their appeal is marginally lifted by an accompanying llajua sauce, which I know as a fiery, chile-based Bolivian salsa fresca, but which here seems to consist of grated tomatoes—just grated tomatoes, with hardly any salt.
