Middle House - Mayfield. Not quite TW either
Wetherspoons in the old theatre....
You can't beat T' Wells Bar & Grill for a Sunday roast, £13.95 and you won't be disappointed. Cracking service and great garden/patio.
I would recommend The Beacon just about 5 minutes in the car from the common. Epic views and fantastic food. The George & Dragon in Speldhurst is outstanding. If you must stay in the centre then I would agree that The Bar & Grill is a good call.
