The Japanese call it Shabu Shabu, my Cantonese family called it Fire Pot. Add the fresh food such as thinly sliced meat, seafood, fishcakes, vegetables and noodles.
The thin slices of meat you get have to be frozen first to be able to slice the meat thin enough. I recommend getting ones rolled up so they are easier to handle.
If you don't feel like cooking at home, The Bay has it covered. All of the places in San Francisco that I have been to have closed, so I've got nothing for SF!
