If you're looking for vintage video games, this is a great place to check out. They stock pretty much every system and even have demo consoles set up to play inside!
If you're just trying to recreate those childhood memories, the selection is amazing with prices being on the upper end of reasonable. If you're a collector of vintage games, keep in mind the store is too and their prices reflect the time and effort they have put into acquiring items.
I haven't been to the other location, but the staff seem very knowledgeable and helpful at the Bell Rd. store. Great place to check out!
