Bold contemporary art decorates this convivial multilevel cave in the same-named Sasso neighborhood, but when it comes to food, it’s all about old-fashioned cuisine—wholesome, straightforward preparations that don’t pretend to be anything other than cucina povera, poor man’s grub. Fresh local produce shows up in dishes like strascinate con rape mollica fritta, pasta topped with broccoli, chili peppers, and breadcrumbs, or lamb fried with onions, tomatoes, mushrooms, and wild onions.
