I haven't eaten at a buffet for a long time. There was one near me that I liked but it closed down, allegedly over health violations but it always seemed clean when I was there.
There's a Chinese place near me that does a buffet but there's only so much appeal to the same dishes again and again. Usually they seem to be priced such that having a plate or two doesn't feel like good value for money but having more leaves me feeling over-full a short while later. And then there are the general concerns of the kind of people who taste food off the serving spoon and then put it back in the dish.
