SBI PO 2015: Letter to the Restaurant thanking them for their hospitality

Hello Readers,
On account of SBI PO 2015 Exam for the post of Probationary Officer, here we are providing you all a letter on “Letter to the Restaurant thanking them for their hospitality”. Hope you like the post!!!
You celebrated your birthday with some friends last week in a restaurant. It was a great success and you and your friends enjoyed the evening very much. Write a letter to the restaurant to thank them. Mention the food, service and the atmosphere. Also suggest any improvements to make things better.
Dear Sir,
Last week on Saturday night some friends and I had dinner in your restaurant to celebrate my birthday. I am writing to thank you for the great evening that we had.
All my friends remarked afterwards on the standard of the food and service that we received. All the food was very tasty and well presented. Our waiter, whose name was Karan, was fast and friendly and put with well with our bad jokes! The restaurant itself was warm and friendly and the atmosphere showed that all the diners there were enjoying their evening.
I would like though to suggest one improvement. One of my friends is a vegetarian and he felt that the choice for vegetarians was little small. If you could develop that, it would be a great advantage to your restaurant.
Once again I would like to thank you for my highly enjoyable birthday dinner.
Yours faithfully,
