Have at least two signature drinks, be able to make both at home – I have five (which may or not be a good thing!) My go-to is either a whiskey sour, a perfect Old Fashioned (learned that from an older guy I worked with once) or straight chilled tequila with no training wheels. And you now what? I know how to perfectly mix the first two and how to offer you the last. Having signature drinks eliminates time wasted debating what to order and builds your projected confidence. You walk into a bar, see your friends and while you’re saying hi, the waitress asks for your order. You don’t hesitate and with a polite smile, you order. Boom. Done. It’s impressive.
