House in the Tree or Pheasant Inn, five minutes drive both do reasonable 'pub grub' lunches, The White House hotel is OK too but the short taxi ride to Cheltenham is probably your best bet. Huge choice from Le Petit Blanc to Burger King...if your Dad's a local he might know a few haunts?
The boys and girls in the Briefing Room will point you in the right direction.
Remember to leave room for 50lt of AVGAS, you'll get a cheap landing fee
