Barton will give you a hearty welcome, but miss the curries.
I had breakfast there last summer and that was certainly something to be missed. Otherwise a nice airfield.
For lunch I'd opt for Old Sarum, followed by Compton Abbas. Kemble is also good. Sandown's new cafe seems very nice, not that I've so far made much use of it. Other nice ones I know of include Goodwood and White Waltham.
