I used be a fan for this place. and frequently be there last two years. However, couple months ago, I went there with my friends (two Asians and one Caucasian). We three were all fine. I don't know what happened to my Caucasian friend. That night he started to vomit and diarrhea, and he is the big fan for this place. After that night, we were not be this place frequently. I think they may just make some one time mistake, but we just could not remember this place when we want to have buffet.
