The Golden Gate Magic Store was a classic magic store in a building,(2nd floor?) upstairs on Market Street. I remember it had long counters of magic, (they looked long to this kid)and a small stage on the right, to demo larger things. Photos of the wall and chairs and I believe a couch(!) for those to sit and socialize.
After Tom Defelulson,(spelling?) a man whose first name was Les ran the store, and I was told later by some, not very well.
About 2 years after it closed Marvin "Buma" Burger opened The House of Magic on Chestnut Street, where it stayed for almost 40 years.
Pete Biro could tell you more perhaps I'm sure.
(Note: It seems many of the BEST magic stores were upstairs...Flosso, Chanin, Berg,Tannen, etc.
