I'm pretty sure it doesn't exist anymore, but back in the 1980's there was a large store along the business beachfront of Long Beach, California. It was on the ocean side of the busy road, but not an ocean view.
Store sold all kinds of sf and fantasy including models, toys, fanzines, books, comics, collectibles. Biggest store of its king in Long Beach.
A few blocks away was a store called Sherlock's Home that sold mysteries.
Does anyone recall the name of the store or even remember it existing?
