The mind is a complicated thing. The way people think and take in the world around them has an impact on all areas of life, including the average meal check at your restaurant. If you feel that your checks should or could be higher, the problem may be not in your food or service, but rather with the psychological effect of your menu design.
The design and strategy of your menu creates a strong psychological pull for your diners, drawing them to certain items and steering them away from others. If you understand menu psychology and implement it with your own menu, your average check will start to increase even without any actual changes to the menu choices.
Eliminate Dollar Signs
When people see a dollar sign, they almost instinctively hold their wallets a little tighter. Dollar signs remind the diner that they are about to spend money, and this can make people spend less. The brain automatically associates a dollar sign with cost, not gain, and your diners will spend less when they see the symbol. When presented with a menu without dollar signs, however, diners will spend more.
