Personally I would drop them a line, saying how much you usually enjoy their food, but on this occasion due to an error on their part you had to drive all the way back (tell them the mileage, there and back) consequently you where highly disappointed and the meal was cold. Although the young woman got you the "forgotten" part of the meal no apology ensued....... if the Manager cares you should get a voucher towards another meal with them......
