Poor Restaurant

I went to this restaurant a few weeks ago and ordered a prawn and chicken curry. When this arrived this turned out to be a shrimp and chicken curry. When I complained, the manager brought a proper LM prawn on a plate and insinuated that that was what was in the curry. He then said the entire meal (including 2 bottles of wine) was on the house! If that is not an admission of guilt then I don't know what is!
