Katana offers a spectacular show seven nights a week in the fine art of teppanyaki, or grilling. This is a Japanese restaurant for those who shudder at raw fish; any steak-loving American will find plenty that pleases. Seven stations are on one side of the restaurant, each with a granite counter wrapped around three sides of a hibachi. Up to 10 people can be seated at each station. On the other side are booths and tables for those who prefer not to dine communally.
