You simply choose what you want from the chilled food bar, place it in your bowl, choose a broth and when it is all cooked, you just collect it and eat.
The price is by weight so some items are definitely going to cost more because of their weight.
Overall, it was a really good experience but if you can't tolerate the spices you are limited to the tomato or mushroom broth which makes it boring.
It would be good if they could have different spiciness levels for the Sichuan broth because I would definitely come back for it.
Having tried the Sichuan broth, it was very authentic but too spicy for me to tolerate hence I couldn't really eat it.
The tomato broth isn't bad as the tomato taste is appetizing and natural but ideally I would love a spicy broth for a hot pot.
