The dollar menus have it all wrong.

A Cornell University study found that diners appreciate their food more if they pay more for it.

139 diners ate at an upscale Italian all-you-can-eat buffet. Some were charged $4 per meal, the rest were charged $8.

Researchers discovered, although the amount of food consumed was the same, those who paid more for their meals enjoyed them more (to the tune of 11 percent), while those who paid less reported bloating and guilt.

People often equate quality with price -- even when that's not the case.

Lobster is a good example. Lobster prices are at an all-time low, but restaurants prices are not reflecting that reality.
