In terms of parking, I would suggest Trinity Road (come in from the top end by the Church and the Mosque). If you have a drive down there, there are usually some spaces to park on the road. If you don't mind paying then you can park in the King Edward's school car park for £5. Only a 5-10 minute walk from there and you do go past a couple of burger vans on the way (a hot dog is my young nephew's number one priority when he goes to a game!).
