First, the burgers. All eight Epic Burger locations around Chicagoland will offer the deal from 11 a.m. to 9 p.m. or as long as supplies last. The birthday bargain includes a single-patty burger and standard toppings — lettuce, tomato, pickle, onion, Epic Sauce — for 10 cents. Additional toppings like cheese, avocado, bacon and a fried egg will cost you extra.
