The melting pot is a fun once-in-a-while experience. It's very social and people who have been here before get to feel like they're showing newbies something, which gives you something extra to chat about.
However, it is no culinary feat by any means. Melt cheese + dipped bread = yummy. Melt chocolate + dipped marshmallow = yummy. Duh.
I've been here for the discounted ladies night and a bachelorette party where they gave use a huge discount too. I can't imagine paying $80 for a couple here, but I guess people do. When folks pay full price for a full meal, the melting pot is laughing all the way to the bank. I think a lot of people who are big fans get in on their discount club thing.
The service is SLOW, which can be nice or annoying depending on the type of experience you want.
