Definitely worth the money! Our (Filipino) chef, was hilarious. Very entertaining and provided great service. While he was cooking, he was making jokes -- appropriate for kids and adults. For birthday celebrations, It was a bonus that the kids got to wear a rubber wig and Japanese outfit. The staff will come around with small drums and sing for the celebrant. They don't tell you there's an extra $3.50 charge, but it's worth it for interesting experience.
We went to the one in downtown Edmonton, but the chef was not entertaining at all. Plus he don't make the volcano on fire (may be a By-Law?). Anyway, if you're in Calgary, definitely book ahead. It's worth it!
