The experience itself was not as exciting as other people mentioned. I went on a weekday so there was only one blind server. The table was equipped with only one fork and the server was pretty busy so she did not bring us water until mid meal (even though we requested several times), did not bring us any napkins (also requested) and did not bring us bread until after we finished our appetizer.
The food itself was mediocre - they were luke warm (maybe they can't have the food too hot in case you hurt yourself? but it was not that good). If you choose a two course meal, skip the dessert- the ice cream tasted like cheap no name ice cream and the cake wasn't great either (probably store bought). I'd say the entree was the best course but I've definitely had better.
I know people say to go for the one time experience but IMO, I would not even go there just to try once. I'm not sure if the experience is better on the weekend but the weekday experience was pretty terrible with bad service and the surprise extra tax at the end.
