Entrée Marché Shin-Osaka Central Entrance Store
Located right outside the JR Shin-Osaka Station Shinkansen Central Exit. Even if you're about to catch a Shinkansen or during a layover, it's conveniently situated for a quick visit. Among the several souvenir shops in the station, this one boasts the largest floor space.
I stopped by to buy some souvenirs for my trip, but the service from the larger lady with glasses at the register was really disappointing. When I tried to take my change, she tossed it back at me. It was the end of a fun trip, so this left me pretty shocked.
