Roppongi is home to Cher Ton Ton – one of the fancier Teppanyaki places. You sit around a very large open grill and the chef cooks its all right in front of you. The kobe beef special is my recommendation.  Definitely a gaijin favorite. The ice cream was homemade and delicious (no picture). http://www.seryna.co.jp/monchertonton/
