Roppongi
In the outskirts of Roppongi there are many foreign embassies, and of course many foreigners about too. There are huge shopping complexes, like Roppongi Hills and Tokyo Midtown, that have many shops and restaurants geared towards foreigners. You can live it up while you enjoy shopping, wining and dining. Roppongi has a great nightlife, but you can also enjoy some culture and see a more refined side of Roppongi with the Mori Art Museum, and the National Art Center.
