As a longtime bartender in this city... if you're interested in working behind the bar, don't go to bartending school. It could be useful for picking up some basics if you have very little knowledge to begin with, but don't put it on your resume or bring it up in the interview. Instead, start as a server or barback and let management know that you're interested in working your way up. Much more practical experience, real people experience, and managers will take you seriously.
