Real Chinese food is most excellent, but Chinese buffetts over here... even on a cheat day I'd say stay away. Everything is fried and drenching in sauce. Even the best of places orders the cheapest meat they can find. Buffetts also encourage people not just to overeat, but to blow right past that point into the realm of pure gluttony. You need to go there one last time to thoroughly examine how cheap and crappy the food quality really is and ask yourself if this is really what you need to be giving your body while trying to give it an overhaul. Most people can't slow down with shoveling in the food to consider such a thing, that's why they get away with it, and that's why alot of people are really overweight.
If you want Chinese food, learn how to make it yourself at home. I promise you that once you get used to preparing stir fry at home and get used to better cooked and higher quality ingredients, you won't even want to go to a Chinese buffet.
