I had the worst experience here.
First of all, the waiter spoke only Chinese to me even when we clearly do not. The waiter did not seem to care if we understand or not. As a result, we had to seat at a table of one stove so we were forced to share one pot. (I realized this later)
Second, my girl friend and myself had no experience in hot pot so we had no idea how to order or eat. The waiter paid very little attention to it and was very not helpful. He gave us very short instruction and showed minimal patience. He walked away without taking any questions. I had to call the waiter for questions multiple times when the restaurant was not busy at all. He was waiting only two tables including ours.
Third, more importantly, even I clearly mentioned I have a Groupon to use, the waiter still let us order lunch menu which I cannot use the Groupon for. No explanations were there and he kept saying he said it when I was trying to use it. When I asked to talk to the owner, the manger kept saying the same thing. "I'm the manager". They neither took the Groupon nor gave me a single apology. This was the worst thing overall.
The only reason why I did not give one star is that the food was okay. Meats, vegetables and noodles were fresh and broths were okay. It was just the attitude of people there makes me never want to go back there again. Be warned before you visit. It is worse than you've ever experienced.
