I personally recommend tourists to go to the underground trail. There are a variety of snacks and a wide range of goods. The lively and endless crowds can rest everywhere when they are tired. If you are hungry, you can eat everywhere. When it snows outside, it is more comfortable to walk in the trail. Metro JR is convenient to transfer, if you buy your favorite Dongdong must remember the location, and then want to buy it is really not easy to find.
