This urban garden is tucked between very tall buildings. It’s a quiet little gem of a space, accessible through the lobby to the rear or via an obscure passage off Front Street.Travertine and black granite flooring, an art piece, plants in containers and designer tables and chairs. Food services on site. Receives no sun, but light colored materials and reflected light stave off gloom. Café closes at 3 p.m., building and garden at 6:30 p.m.
