If you want to get a sense of how much they love local ingredients at Beba, you should witness (as we did) the joy that greets the arrival of a crate of oyster mushrooms. Seasonal produce is key to the ever-changing menu, which is inspired by the Spanish and Italian migration to Argentina, and might feature options like chard-wrapped involtini, guinea fowl, golden brown empanadas, or the remarkable silky flan with dulce de leche for dessert. Use this place for a nicer meal with your significant other or a small group, where you can sip from their thoughtful wine list that features both new- and old-world producers.
