Top of Shinagawa (CLOSED)

It's a fairly standard fancy hotel bar, except for the view: the Shinagawa Prince Hotel's top-floor North Bar offers some pretty damn impressive vistas, with Shinjuku's skyscrapers, Tokyo Tower, Roppongi Hills and the Skytree all visible from here. Drinks start from ¥950, while the two neighbouring restaurants (Prince Court and Sky Dining) offer buffet lunches and prix fixe dinners respectively.
