Shibuya

Shubuya is one of the busiest shop and restaurants areas in Tokyo. The amount of people here is amazing, better not stop walking in the middle of the street of you'll be ran over...This district is popular for teenage girls because of the shops. Most of the people I saw here were pretty young...

I went to have lunch in a small restaurant and many of them don't have cashiers, they work on wending machines. There are pictures of the food, just put the money in and choose your meal printed on a paper. Then give the little paper with the name of the food to the guy behind the counter. Smart, easy and fast!
