We went to Yamato based on a few reviews on CH.
In the past I have taken groups to Bennihana for teppanyaki but I thought I would make a change this year.
It was a good decision.
Our whole group had the Imperial teppanyaki, which is beef tenderloin, shrimp and chicken. The meal starts with a miso soup followed by salad with house dressing.
Then out come the chefs. We had three different chefs. Two were outstanding and one was just OK. He was good while at the table but he rushed through things so fast that he was done in half the time of the other two.
The food was as good if not better than Bennihana, allowing for the fact that you are never going for fine dining at a teppan restaurant, and the show was definitely as good or better.
Our meal at Yamato with a half bottle of wine per person cost considerably less than the equivalent meal at Bennihana with a glass of wine.
I highly recommend this place.
