Dear Sir/Madam,
 
I and my friend visited your restaurant yesterday to celebrate the beginning of our vacation. Unfortunately, the substandard food served in your restaurant really dampened our spirits.
          

 Firstly, I ordered salad, but it was not fresh. Furthermore, the vegetables had not been washed. I found pieces of dirt on the lettuce leaves.
           

Then, I was served a really tasteless steak. It was tough and chewy. I called the waiter to bring me new steak. After waiting, the waiter finally came and gave me a new steak. To my astonishment, it was as bad as the first one.
           

As if that was not bad enough, when I decided to eat my apple pie, I found out that it was stale and dry. Once again, I called waiter, but he claimed that it had been freshly made that morning.
           

As you can imagine, I was extremely upset by the treatment I received and I will certainly not visit your restaurant again. I hope that in future you will take care of these mistakes in order to prevent them 
 
Yours faithfully,
Name
