I have had hot pot in various cities in North America. I enjoyed Legend Hot Pot on several times.
They do often miss orders of dishes, but seeing as it is all-you-can eat, eventually after a few rounds you're bound to have everything on the menu.
Service is overall, great. A couple of times, I felt like the hostess/host did not know how to prioritize the needs of waiting customers with the needs of other customers already in the restaurant coming up to them and interrupting.
I recommend this place when it isn't as busy. Food itself is fresh. Selection is great.
