Roppongi Crossing

Sure, it's ugly, noisy and can attract some unsavoury characters, but Roppongi Crossing – the area's symbolic gateway – has a buzz that few parts of the capital can match. Start walking south along Gaien-Higashi Dori and you can enjoy good views of Tokyo Tower (assuming that you aren't too busy dodging drunken revelers and fending off touts, that is).
