I came here in the end of August 2014 with a group of 6 so it was only 1/3 full as it was summer and I guess not a lot of people eat hotpot in the summer. You choose the sauces you want and they bring it to your table. The service was very speedy. They also brought two pitchers of lemon tea and plum juice (included in the AYCE price) which were satisfying. We stayed for over 3 hours and they didn't rush us to leave, but then again it was summer so it wasn't busy anyways.
The parking lot is pretty big and wraps around so I never had trouble finding parking.
I will update this review if I come during the Winter as it seems like people have a lot of issues with the service during Winter!!
