It's great that we could find something to eat at 2am when jet lag messed with our eating schedule and nothing else was open except the four 24-hour chain restaurants, 6 full-service Izakayas and a late night curry shop within a 5 minute walk. What would we have ever done without a choice of 6! different convenience stores within the same area?!
Oh and on the way there's vending machines literally jammed into every available urban crack that can fit one where I can service most of my beverage and a few food needs.
I couldn't figure out how these places earn enough money to keep the lights on given the competition, now I guess I know.
