If you're new to "hot pot" then this is a good place to start. Everyone gets their own little pot of hot broth to cook in at their own pace. Don't underestimate the amount of food they bring out, you definitely won't be able to finish it all. Worth the experience!
If you're new, this is what to expect when you sit down: pick one of the "combo plates" that come with a type of protein (shaved slices of beef or chicken or lamb, you get the idea) and then a broth flavor. My table ordered the spicy broth as well as the Korean kimchi broth and both were delicious and importantly, not too spicy - like a 6 out of 10 spice level. I suggest ordering off the ala carte section and getting udon noodles.
