It is probably a bad sign or the waistline when the manager of a Chinese Buffet knows you on sight, knows exactly what you will go for on the buffet line and brings you a glass of your preferred beverage before your arm is out of your coat sleeve. But it is a very good sign when it comes to service.
If you are looking for a decent Chinese buffet with a friendly staff and a wide selection of great food, you might consider a trip out to Monroeville. The food at City Buffet is almost always hot and fresh and there is something to please everyone in the family. (As with most buffets, you have to go there at peak times. You can't go an hour before closing and expect the food to be all that fresh.)
Even though it has been renovated recently, the decor is not the greatest (like someone took a typical kitschy Chinese Restaurant circa 2000 and dragged it through the 1980s) but it is something I am willing to tolerate in the name of satisfying my deep spiritual cravings for won ton soup and a little sesame chicken.
I don't care for sushi, but my Japanese friend has assured me that it is actually pretty excellent and it is made to order. If the egg rolls are a little lackluster, I find the rest of the food is excellent. Just keep your eyes out of the black pepper chicken. Its mine. All of it.
(This establishment used to run under different management under the name "Evergreen." It is a completely different place now and has been so for 2-3 years.)
