My family went to the restaurant, Little Sheep Hot Pot to have a nice hot meal on a chilly day. (Note: This picture is from December in the SF Bay Area.)
The hot soup, is placed in pots over burners set in the table. Then, raw meats, vegetables, etc. are brought to the table and you cook it in the boiling soup as you go. Of course, if you end up overcooking or undercooking the food you only really have yourself to blame. That or the other people at your table ;).
