Back in the 1970s there used to be an outstanding chinese restaurant called Shanghai. Just south of Menual on the east side of San Mateo (off the little side street behind the Denny's and that La Quinta inn). Southwest Cover Specialists are there now.

This is a long shot, but does anyone have pictures of the restaurant inside and out?
