I give this place a temporary 2. They always say that you should let a restaurant work out its kinks before you go. I guess they were right. Both times I have went to Top Shabu-Shabu, the service has been pretty terrible. You write down your selections for your pot, but then the servers just bring it all out an once. I was with a group of 8 and it was a nightmare trying to figure out who order what. The staff constantly brought wrong things and constantly forgot items.
However, this is the most authentic style hot pot in Pittsburgh. The food is quite good and reminds me of Asia. You can believe me because this place is always filled with Asians.
Now, on my most recent visit, we had a pretty horrible experience. I found a rubber band in my vegetables. I only figured it out as I was stirring my pot. I have no idea how long I was cooking the rubber band or how it got into my soup.
We argued back and forth in Chinese. Their only solution was to offer me 10% off my bill. I wasn't in the mood to make a scene I accepted this, and they gave us all free dessert.
I won't be back for awhile, but I will eventually go back.
Be sure to try the ??, or as they call it, the Chinese fritter!
