If you took our earlier advice and started getting into the habit of drinking with your friends before you go to the bar this will be a lot easier. Since you're already all hanging out together, take the opportunity to order (or perhaps even prepare) before you hit the bar. If you arrive at the bar hungry, you're going to make some pretty awful food decisions once your a few drinks in. We're sure your own personal experience can probably confirm this. Take the decision out of the equation early by getting some good grub when you still have your wits about you.
