Official opening day for Sra. Martinez, the new tapas place from local hero Michelle Bernstein in the old Post Office building in the Design District (a/k/a the former Domo Japones space), is Monday December 1 (Dec 1 may already be fully booked as there was no availability on opentable; I'll be there Dec. 2). They're starting with dinner service Mon-Sat, including late hours Fri and Sat till 2am, and eventually will be phasing in lunch service too.
