For six magnificent weeks until 31st August 2014 you can get two handcrafted burgers for £10. We've partnered with Absolute Radio, so that for every voucher redeemed you'll be helping to raise funds for Shelter.
Head over to Absolute Radio to download the voucher and to enter our competition to win a 16GB iPad Air with retina display & Wi-Fi. If you win? Be rewarded for your burger hunger by dowloading the GBK app. If you don't, download it anyway to earn free burgers & sides and complete challenges.
