@spendius,
A Chinese buffet, my dear sir, is my shorthand for a buffet meal in a Chinese restaurant.
Quite a few restaurants now (there's a big Asian...Bangladeshi probably...one near here) are set up for "all you can eat" deals, probably cutting down on the number of serving staff, and pandering to the gluttonous tendencies of the populace.
There's a quite big Chinese restaurant in the centre of our town, and the buffet type of service is all they do. Good variety, reasonable quality, quite nice for a change now and then.
