Los Angeles restaurant Not A Burger Stand offers discounts to people who order in the voice of a specified character. From Frozen's Olaf to Game of Throne's Little Finger, talented impressionists often receive 10% off. There is usually an added incentive related to the character as well. For example, patrons who order with a Dobby impression get 10% off, but showing your Hogwarts acceptance letter means it's free.
This creative initiative is likely to attract new customers as the signs advertising the pop culture character of the day sits outside. Given Not A Burger Stand is located in LA, there is no shortage of people who specialize in voice work either. The family style restaurant is also likely to appeal to young kids familiar with the characters.
