There is a good buffet called New York China Buffet on 535 near Cypress Pointe. Like most buffets, the food suffers if it sits too long, so I only go when they open at 11am.
They have a great variety of good dishes at a low price (around $7, coupons can be found in orange Orlando map).
It seems to be popular with locals and Disney employees. It is so strange to see employees in their Disney uniforms off site.
