Mexican folk art and plentiful paintings of Frida Kahlo fill this cozy downtown hideaway for wine, elegant shareables, and conversation. Get the grilled lamb pops with a Moroccan-spiced carrot puree and the smoked salmon croquettes, revved up with a piquillo-tomato chutney. Tops among meatless tapas: the potato-Swiss cheese tortilla, sweetened with herbed caramelized onion.
