We love Teppanyaki and it is a must on each of our trips. My son chose it for his birthday dinner this year. As others have said it is in the "Benihana style". You sit at tables for 8, so if your party is less than 8 people there will be others seated with you. You sit around the grill, which is in the center of the table. The chef is the entertainment, and most are very entertaining.
The food is "stir fried" and great. We always get a combo meal (Scallops and Steak for example) and it comes with white rice. Appetizers and dessert are available (and included in the Dining Plan), as are drinks. The Lobster is now considered an add on, not a combo meal, so it is not included in MYW Dining package. The Sushi is no longer allowed as an appetizer on the plan.
The staff and servers are warm and friendly, the chefs are, for the most part, very entertaining.
We love this place, I hope you will too.
