Enter to win free burgers for a year at Gwinnett restaurant opening

A new Gwinnett hamburger spot is celebrating its grand opening with a challenge to eat a nine-patty burger as fast as you can.

Wayback Burgers, a fast casual chain, will open in Lawrenceville June 23. In addition to giving away free burgers with a purchase during its first two days of operation, the restaurant will hold the “Triple Triple Contest” at 2 p.m. June 24.

The “Triple Triple” is a nine-patty burger on the restaurant’s menu. The guest who eats the sandwich the fastest will receive an unspecified prize. Diners will also have the opportunity to enter to win free burgers for a year.
