Dear Mr./Ms. (Don't ever use Mrs., even if you know. Ms. doesn't carry any information about marriage (it's not the same thing as Miss)) My name is [your name], and I am very interested in gaining employment at [restaurant]. I feel that I would be a good fit for [position] because of [reason A], [reason B], and [reason c]. I've attached my resume for your consideration (put it in PDF format; almost everyone should be able to open that). Thank you for your time, [your name]
