The other side of a modern office district
This area, called Shio-dome, is one of the biggest skyscraper area in Tokyo and contains luxury hotels, together with some TV broadcasting, advertising, cosmetics, airline companies.
This is basically business district while this has some sightseeing spots. With so many people, they are always running short of restaurants. So people there need to wait for lunch in front of restaurants. Or, they need to go other district just to have a lunch.
They are called "Shio-dome refugees".
PS. I would think that big business chances are waiting in Shiodome because of lack of restaurants.
