Spices, peppers, broth are heated to boiling and you cook your own meats and veggies you order as the meal progresses. There are many hot pots I have had (the one using fresh coconut water is my favorite) but you cannot be in Sichuan province without trying theirs. It is considered the hottest.
The next night we went to a different hot pot place. Again we had the bone broth in one side and hot pot on the other. It definitely gets hotter in spice the longer it cooks. The bone broth did not have heat to it so added some of the other liquid to give it a kick.
Excellent hot pot and trying different meats, fish, and types of veggies. Definitely a reason to visit again!
