OG Sydney food truck Mister Gee has accumulated a city-spanning fan base since it opened its first truck in Burwood in 2014. Six years on and the burger joint is ringing in its birthday with a two-day celebration kicking off with free burgers.

The first 50 customers to arrive at each of the Mister Gee Haberfield (at 315 Parramatta Road) and North Strathfield (at 16 George Street) stores on Friday, November 27 will receive a free burger. The freebies are sure to go fast, so you'll have to get there bang on opening time at 6pm to ensure you get one.

If you do miss out, there are burgers on offer over the weekend for $10, which also included a free bottle of Jarritos soda. All of Mister Gee's fan favourite burgers including its truffle burger, Vegee Burger (with a vegetable patty, cheese, pickled onions, tomatoes and special sauce) and The Stoners Revenge (which features beef, cheese, bacon, onion and chips) will be on offer for $10 from 6–9.30pm Friday, November 27 and Saturday, November 28.

Live street artists, DJ sets and a photo booth will be on hand to bring the atmosphere to both locations as Mister Gee celebrates a half-dozen years of serving Sydney burgers.
