It's not tobacco, it's ice cream, dummy.
So this is another form of hotpot which is somewhat different from Chongqing hotpot and it's called 串串香 (Chuan Chuan Xiang). You go pick the ingredients you want on skewers and you simply pay for the amount of bare skewers left when you're done. The awesome thing is that the characters in the name of the dish are little skewers, how cool is that?
@ttyr believes Chongqing hotpot to be superior to Chuan Chuan Xiang. This is serious.
