Aladdin's buffet is pretty good for the price. Not too far from NYNY either, IIRC. You shouldn't be down there anyway, but if you are, avoid Circus Circus's buffet. Especially at breakfast. If, by chance, you are forced at gunpoint to eat at circus circus's buffet for breakfast, do not eat the bacon.
Ceaser's Palace is unbelievable. When (and if) I ever return to Vegas (not likly unless for a convention), I'll be staying there. Check out the Forum Shops. When I was there, the Versace shop was closed cause he had just been shot the day before.
