We tried the melting pot recently and it was ok. But IMO, if you want to do the fondue thing, go to Kiku in Station Square and order the Shabu Shabu. It’s awesome and will probably run you $60 for 2 people. It’s all beef and vegetable and when you are done with the beef, you have a soup at the end.
Casbah, in Shady Side, was really good. I went there several years ago for a friend’s going away dinner. http://www.bigburrito.com/casbah/ It’s one of those Big Burrito restaurants.
