The Great Wall is the best Chinese restaurant for lunch buffet. Unlike other Chinese places, the buffet is very lavish with enough varieties of dishes to suit everyone's palate. The service is quick and prompt. In spite of its massive popularity, there is very little wait time and more often than not, you get immediate seating.
PROS: seating space, parking, all day buffet
CONS: traffic, a la cart emenu is not very good, limited drink selection
