I agree with FFF about the Red Lion (follow Stoke Poges signs from A412 Uxbridge/Slough road).
Also worth a try is the Crooked Billet, on the A412 at Iver Heath. It's an "Out and Out" (if that means anything to you).
For Indian, best I know in the area is The Prince of India in Gerrards Cross.
Hope this helps.
