Girl wants to meet for drinks but... I don't really drink WHAT SHOULD I DO?

There's a good chance she said "meet for drinks" because that's the only suggestion she knows for a way to meet someone and initially spend some time together and assumes that most guys like to drink. Let her know you're not really into drinking and suggest another activity. If she wants to be drinking more than just getting to know you, and doing something else, she's the wrong girl anyway.
