Folks the best thing to do is speak to the RGM (restaurant general manager) tell them how often your going to go and you would like to enquire about some discount

Ask them for around 25% The same as the Whitbread cardholder discount or ask for the Police level discount if thats no joy at 10%

Its always worth reminding them that you could always go to KFC or Nandos or whatever else is on the park (tell them that they have offered you 20% to go there but you like P hut)
