*Terms and conditions: Lunch on your next visit for free. Valid on the lunch menu, to a value of £6.95 only. Does not include lunch menu upgrades to 6oz. Valid at GBK restaurants in the UK mainland. Not valid in conjunction with any other offer, set menu or reward on the GBK app. **6oz beef patty or large bean patty or chicken. All our beef burgers are cooked medium unless specifically requested otherwise. Burgers cooked medium rare carry a higher risk of food poisoning. Unlike a steak, a burger needs to be cooked through to reduce that risk. The Food Standards Agency recommends that children, pregnant women and anyone with a weaker immune system have their burgers well done. We use lots of different ingredients in our kitchens so cannot guarantee that our food is completely free of any allergens. If you require allergy information, please ask one of our team. We change our recipes from time to time, so please check regularly.
