Little confusing if it your first time there. I been to hot pot restaurant before but still have to ask the waitress to explain it. Going there with 2 person and the bill come out to 60 something so warning, is can be a little pricey.
When I was there, the table next to us it finishing up and leave. They clean up really fast but in the middle of the cleaning, cashier lady from the front come in, get a clean plate put the half eating vegetable (lotus root, more pricey vegetable) and bring it to the back of the kitchen. I dont know why she did that when there a trash can right there on the cleaning card. If i have to guess, feel like they reuse it. Anyway the food it ok, dont think i come back because of that.
