Seriously Hungry Right Now: Need an excuse for a #primeburgeruk during the school break? Kids under 10 eat free until 6th June @primeburgeruk #nomnom #theartofplating #burger #burgerporn - t&cs apply. Ask staff for more details but basically to get free kids food, you need a kid with you. You need to buy something for yourself or an another adult to qualify. Actually if there are a few of you, all buy something and after about 25-40 minutes, you'll feel a lot happier!
