Be prepared to smell bad after you leave a Melting Pot. When the wife and I go, we prefer the coq au vin instead of the cooking oils for our meat, and even that way, our clothes smell like we've been working a double shift at Wendy's afterwards.
The easiest deal is to get the three course dinner, which actually includes a small salad, followed by a cheese fondue appetizer of your choice, followed by the entree collection of meats, and then a chocolate fondue dessert of your choice.
Here in Atlanta, I think we paid about $100, inlcuding a couple of drinks for two people, which, for that money, I can eat a much nicer meal elsewhere. I'm not poopooing Melting Pot, it is a unique experience that should be enjoyed at least once, but if you are going under the pretense of fine dining, keep looking.
Edited to add that normally I'm not a big fan of 'sauces'. If the cook intended a sauce for a dish, then so be it, but I hate the little sides that accompany the entree because if the meat is good, it doesn't need anything else. That said, they include a Green Goddess dressing with the entrees that is absolutely perfect with a hot cooked mushroom. Even when the meat is long gone, we will often get a refill of veggies for just that tender bit of divine morsel.
