tonight was hot pot.

If you've never had it, it's one of the most fun and tasty casual kind of dinners you can do. My favorite part is, of course, grilling the super thin-sliced meats around the outside of the soup pot, and concocting a dipping sauce to my own taste. Plus looking at all the weird tentacles and crap on the buffet next to the cut up hot dogs, vegetables, fish, and other assorted goodies.
