Basically, it is an ice cream sundae delivered in a large bowl shaped like a kitchen sink complete with faucet and handles. Many scoops of ice cream, every topping you can imagine...shortcake, brownies, chocolate bars, various sundae sauces, whipped cream, cherries (we asked for our without the cherries, since they usually put on many !!!) Our family of four ordered it for my DD's birthday lunch, the sundae was the lunch and we couldn't even get close to finishing it.
The kids loved it, but as adults, I don't think we would do it again. It was fun to try. There are a number of pictures of it on the dining picture thread. Also, there's a link to a video about making it but it didn't work when I tried it this morning. If I'm successful later today, I'll post the link.
