Dear sir
I am writing to enquire if you have any vacancies in your company. I enclose my CV for your information.
As you can see, I have had extensive vacation work experience in food and beverages and room service restaurants, giving me varied skills and the ability to work with many different types of people. I believe I could fit easily into your team.
I am a conscientious person who works hard and pays attention to detail. I'm flexible, quick to pick up new skills and eager to learn from others. I also have lots of ideas and enthusiasm. I'm keen to work for a company with a great reputation and high profile like Marriott hotels.
I have excellent references and would be delighted to discuss any possible vacancy with you at your convenience. In case you do not have any suitable openings at the moment, I would be grateful if you would keep my CV on file for any future possibilities.
Yours sincerely
Restaurant manager
