The store name and address is Big Lou's Toys & Collectables, at 5413 Sepulveda Blvd (almost opposite the ToysRUs).
(some photos of the store
can be seen here)
A map I did up for last year in case I had time to check it out between flights, and for Fatbot to use while in LA if he wanted to check it out as well...

I can't believe it has been a year and a half already since we (UltraMarginal and I) were in LA for the convention and Hollywood tours... it just feels like it was the last BotCon trip from last year, not the year before.
