Write a letter complaining about meal to the manager of the restaurant.

Dear Manager   Last night (December, 15) I was having dinner at your restaurant. I am unhappy with the quality of your dishes.  Firstly, I had to wait for my soup for about 40 minutes. And when it was finally brought, it was cold. The bread was not fresh. And the fish was oversalted. I feel this is  absolutely not of acceptable for such a well-known restaurant as yours.   Yours sincerely,   Mr. Smith.
