Restaurant week is where restaurants have a prefix type menu for both lunch and dinner which allows people with a limited budget to enjoy a meal at an establishment which they would normally not go to or have been wanting to try. Amex sponsors it and provides restaurants with more visibility. In essence you are still paying for the food.


Physically using coupons and promoting your restaurant like buy one entree get one free is a gimmick cause there is no reason to give food away for free if its damn good.
