I took this trip in May of 2010. If OAT has not changed it, then it could still be the same as when we went.
In my opinion, the dinner itself was good but the show was not very well arranged. Everyone in our group went, because that was the first opportunity we all had dinner together as a group.
The restaurant did not have a stage, the dancers just danced in the small space between guests' dining tables and the buffet serving table. (Other dinner guests that were not OAT members were also in the same dining room. I believe OAT paid to have these dancers come to dance for us.) It was a bit akward that while the dancers were kicking up a storm the food on the buffet table were just behind them.
The restaurant was in a very nice setting. I'd prefer just the dinner without the dancing part.
