Was it a fondue restaurant, like the Melting Pot chain? If so, that’s all part of the deal. It’s actually kind of fun.
Now if you went to a steak place and they had you cook your own food, that’s not right.
Rate things are going, they'll make you slaughter the cow.
I used to go to a restaurant outside Heidelberg, Germany called "Die Kartoffel".
They bring your meat order to the table on a 500 degree stone tablet and you cook the meat in front of you as you talk with friends and get drunk.
Truly a wonderful place. One of my favorite places when I was stationed in Germany
