It's not a zoo, but it has plenty of wildlife. Packed with restaurants, as well as nightclubs and establishments of lesser repute, Roppongi after dark is just plain raucous, and it keeps right on rocking through the night. Defined by the Tokyo Tower at one end and the Tokyo Midtown high-rise development at the other, with several foreign embassies in between, the area is a magnet for expats, overseas travelers and Japanese revelers who enjoy spending time with foreigners. Roppongi caters to Americans in particular by offering up the familiar, in the form of a Hard Rock Cafe, McDonald's and late-night doughnut shops. In addition, the Roppongi Hills entertainment, shopping and business complex has become a mecca for trendy Tokyoites and out-of-town visitors.
