Convenience Store "Buffet Pizza" is a brand, not a way of serving pizza. Herebouts, every BP/Amoco makes/sells "Buffet Pizza" brand pizza. started about 2 years ago, iirc.
the pizza's are about 10 inches or so. the crust is thickish. sauce good. lot's of cheese. toppings are "free".
The cut them into 4 slices, then they box those slices, and put them into a warming machine near the counter, so that you can by a "slice".
if fresh, they are very good. if not fresh they are bad like most not fresh food.
i have a feeling that if you don't like fast food, or convenience store food (2nd best fried chicken in town, till Gus's put a shop in they were 1st, is at a gas station.), then you will hate Buffet Pizza.
If you like that sort of food (have you ever asked, "extra MSG please?"), you will most likely fall in love with Buffet Pizza.
It is expensive, though, as are all foods at a convenience store.
as for buffets at restaurants that serve Pizza, Pizza hut's lunch buffet is an excellent, cost-effective way to stuff yourself sick during the lunch hour. My esteemed Buffet Colleage is correct, during a busy lunch hour the buffet's pizzas get eaten so fast that they will stay hot and fresh due to replacement at quick intervals. plus salad bar for those that think roughage is a good idea before eating massive quantities of doughy product covered with gobs of CHEESE.
PS-
