I love this place, Odaiba. It is one of the less crowded shopping or hang out areas in Tokyo. B4 reaching there, u are treated with a harbour view from the train ride. Shopping is fun: so many shops with reasonably good pricing. There is a shoe shop with low prices but if u have big size foot of 10 or above-tough to get a pair.
Managed to get discounted items like Marvel tshirt from Disney store (50% off). Probably bcos I was lucky then.
When u want to chill n relax, u can just get to d deck area and enjoy the view of the Rainbow bridge.
Didnt get much time to venture to all the shops. Didnt even get time to go to Aqua City. To visit all major shopping centres, Tt probably could take 1 whole day.
