Hi Miqs, just follow the road to the Power Station and after passing Prospect Cottage, the former home of the film director the late Derek Jarman, continue on to The Britannia Inn.
Shepherd Neame ales and although I can't vouch for the grub, as we ate later back in Rye, it does do food.
You can see the Light House in the bg - Big car park btw.
edit:
Food in Rye :
Ypres Castle Inn - Rye - Loverly grub - I had the bangers and mash and some crazy 7% ale
