This post will probably be moved as it is a chain, but I've been to the one in Minneapolis. The servers spend a great deal of time explaining fondue, a bit too much.
The food is very good, many options(bread, veggies and cheese for apps, different meats, fish in oil for mains)but pricey. But after fondue for appetizers and for entree, we went elsewhere for dessert. It got old quickly and was almost 3 hours for 2 courses.
That said, I would go back for apps and wine or just for dessert. Just not an entire meal.
There are non fondue entrees available as well.
