If you're sticking to the east coast then Sandtoft isn't really in the equation!
You could always drop in at Skegness, there are about 20 million chip shops/greasy spoons within ten minutes walk.
Edit: almost forgot Boston which is on the coast, there's a restaurant at the end of the airfield. Also there's East Kirkby just inland from Skegness which is the aviation museum where they keep 'Just Jane' the taxiing Lanc, well worth a visit which has a good caff, don't think they do fuel though but worth asking. (They must have some to run the Lanc)
