Melting Pot is a very special treat. Both times I've been to this location, we've used a groupon. The groupon helps, but doesn't include dessert or cheese sauce, so we still rack up quite the bill. It is definitely a special occasion type of place.
The food is good. I like that you can choose multiple meats or "proteins." It is a fun experience to cook the food yourself.
My only qualm is that servers seem to always be pretty busy and aren't at your table often to help. There are certain items like veggies and dippers that are "unlimited," but there's never anyone around to ask to refill you before its time for the next course. Same goes for sauces. They give you pretty small servings of sauces and in my experience, we usually have 1 or 2 favorites that are depleted pretty quickly, but we can rarely find someone to refill them for us.
