Grand Chinese Buffet

I have eaten here multiple times prior to tonight and have found this restaurant to be one of the best in town. Tonight I was there and the buffet was Cold.  The FDA says that food should be maintained at 140 degrees or more to be safe. The majority of the food on the buffet was little more than room temperature. I mentioned this to the owner and he told me the AC was making it cold. That tells me the food has either been on the line to long or he has steam table problems. Either way this was a lame excuse for potentially getting someone sick with food poisoning by not maintaining safe food standards. This lack of concern worried me and I doubt I ever return.
