"Sing for Your Supper" on Tax Day.
Since nothing in life is ever really free, of course you'll have to work for it—first, you have to be at least 21, and second, you'll have to sing for it.
In case you're wondering what makes the Legendary Burger so "legendary," their menu describes it as "a juicy 1/2-lb Certified Angus Beef® burger topped with smoked bacon, cheddar cheese, golden fried onion ring, crisp lettuce and vine ripened tomato."
It also comes with a side of fries.
The free Legendary Burger will be offered from 12 p.m. to 2 p.m. and again from 5 p.m. to 7 p.m.
