Summary: Russian Hill’s beloved Spanish restaurant Zarzuela will close in November as its longtime chef-owner Lucas Gasco retires and moves to Spain. The tapas spot has spent the last 24 years at the corner of Hyde and Union streets. Next in line for the building: Michael Pawlik, the executive chef of nearby Frascati. Pawlik and co-owner (and girlfriend) Amanda Banks Barker plan to open Abrazo, a Mediterranean restaurant with Spanish influences in the former Zarzuela space.
