Dear Craig,
Patrick and I just wanted to thank you for the wonderful job you did with the catering at our wedding.  In all honesty, your food was the best I've ever had at any wedding, or indeed at any catered event.  Everyone raved about it!  You staff was excellent and very professional.  My every desire was anticipated and met!  It was a pleasure to work with you and I would be happy to give you a recommendation at any time.
Sincerely, 
Angela C.
