What is the error. voted bostons best restaraunt three years in a row?!

Bostons needs an apostrophe, voted should be capitalized, and restaraunt is spelled wrong.

This sentence is part of an advertisement to show possible customers that the restaurant was voted as a great restaurant. The sentence should be: "Voted Boston's best restaurant three years in a row!" Since the sentence is an exclamation, often the subject is eliminated which makes the first word of the sentence voted. The first word in an sentence must be capitalized. Boston should have an apostrophe because the restaurant "belongs" to Boston. By stating that the restaurant "belongs" to Boston, it gives the restaurant a home and a following. It makes the restaurant more like a special place just in the local area.
