 A Nintendo game'nwatch? You can find it here. From large 6 story super stores, to wild superpacked little shops which fill evvery alley. each little shop specializes in onething, so like one shop will only sell LEDs, another, little pieces of metal, andother sells spy cameras. You name it, it is here somewhere, and someone wants to sell it to you.

This photo is in the supr store area, more uppety and more expensive
