Hot pot s is Classic Sichuan food. Large bowl of soup/sauce in the middle of the table, perched on a gas hob/burner. Most often the metal bowl has a barrier vertically across the middle, so that a red, spicier soup is in one half, and a white, less spicy soup is in the other.
Your order food and you can decide what to put into the bubbling soup. Sliced pork and beef, vegetables, doufu, and mushrooms are all standard fare, and you can also get kidneys, liver and many other body parts for the soup.
