I love the Melting Pot. Its not somewhere I'd go daily or anything but once in a relationship (or once every 6 months to a year, whichever comes first) I do enjoy being taken there.
I like going to the Melting Pot on a date as opposed to with a group because its much more intimate to feed just one person a chocolate dipped strawberry than it is to try to feed 10. Sticks cross and that can just be uncomfortable.
Make reservations always as it tends to get busy, as request a private table where you are separated from the rest of the restaurant by a curtain for a more intimate vibe. No one needs to see what you're doing back there with cheese and marshmallows (not in the same course) and whatnot.
I like the fondue for two, which includes 3 courses and a salad I believe, but come hungry because its a ton of food. The wine selection is good and drinks are typically pretty strong. Prices are higher than other places but for the ambiance and uniqueness of the food, and the quality of service, etc, I think its just about right for a special night out.
