If you're ever in malaysia or singapore, you should try their version of hotpot called "Steamboat"
The biggest difference I can find is that the soup is a lot hotter and the dish is mainly seafood based. Also the chilis peppers and sauces used are a lot more potent and spicier.
Also, it's incredibly cheap. For a group of 12 we only paid $50cdn and we got to eat all kinds of seafood.
