Super Potato Akihabara

Super Potato has nothing at street level. The shop starts on the third floor of the Kitabayashi Building, a minute from Akihabara's Electric Town exit, and fills the third through fifth floors with tight aisles.

Most people come for the fifth floor, a small arcade of 1980s and '90s tabletop cabinets you can sit down and play, with a counter of cheap old-fashioned sweets beside it.

The third and fourth floors are for buying, and a test bench lets you try a cartridge before you pay. The PC Engine section runs unusually deep, with plenty of shooters and plenty of games from Compile. If you are after one particular game, phone the Akihabara branch ahead and the staff will check the shelf for you.
