Chefs Alex Figura and Spencer White have made waves with their pop-up dinners at Uncle and Hop Alley over the last few weeks as they preview their forthcoming restaurant, Dio Mio. While it seemed that the waves had leveled out, they came back with a Facebook event promoting a first-come-first-serve dinner at Salt & Grinder from chef Frank Bonanno’s West Highland sandwich shop. While details about the pop-up dinner are scarce, we know that house-made pastas and Italian dishes are expected.
