Do you really want to know? It's a lot of fun. The wait staff start yelling ketshup! Who has the ketshup? And all the people in the restaurant that have a bottle of ketshup will bring you one. Then when the next person asks, the same thing happens to them and so on and so on. They interact with the kids in other ways also. We really liked it but I saw some that were really uneasy. I guess it is how uptight you are. If someone gets a cell phone call they have a lot of fun with that.
Thanks! My 4 year old will probably think everyone has lost their minds. We're going our first night so hopefully she won't be too tired to participate.
We had a group of ten last October, and (of course) asked for and received ketchup. When the table next to us wanted ketchup, someone from our party accidently tipped over their creamer when making his delivery (it was an adult). Our server found out about it and made him ride around the room on a stick pony as punishment for being clumsy.
He had the biggest smile on his face while doing it.
IF you need or want ketchup, just ask for it. Its much "worse" if you are caught "borrowing" some from a table that has asked for it. The following pictures show what happened when a guy sitting near us didn't ask!!
