I was used to getting pizza in the alley way alongside the old Federal Reserve Building (there was also a falafel stand, owned by the same couple, and a caffe that changed names/hands several times). Anyway, all of these businesses are gone! Any suggestions for decent [made from scratch?] single-slice pizza in the area? How is the place in the walkway between Embarcadero 4 and the Hyatt Regency?
