Invitation to lunch at a restaurant.
Can you have Lunch with me someday next week? There are one or two matters I should very much like to talk over with you and upon which I would value your opinion. Would Sunday suit you? If so, I suggest the McDonald Restaurant at 2 P.M. Let me know if this is convenient to you and I will book a table.

I shall be delighted to have Lunch with you on Sunday and the time and place you suggest suit me excellently.
