This buffet is really good if you time it right. As with any buffet, you're going to have the following: obnoxious little kids running around the food counter giggling. Ridiculously large parties where everyone is yelling. People picking at things. And of course, lots of waste. Its always painful to watch.
But with that said, the food here is generally quite high quality. Go during a busy time when the turnover is high and you will get great food. One of the cooks there used to work at Sababa (a favourite middle-eastern place of mine) and they have dishes there that are only really possible in a mass-consumption sort of situation: a whole stuffed lamb (really good but horribly unhealthy!),
I would steer clear of the seafood (the preparations they have are not particularly middle-eastern - I suspect they are just filler and to have a seafood option). They also have shawarma which is pretty good, but its off the menu. You can ask your server for it and they usually have it.
