I don't really drink - girl wants to meet for "drinks" what to do? NEED ADVICE!!!!

You could also go there after she arrives and then see what she looks like. If she is not very attractive, pick out some random guy in the bar and call her and describe what he is wearing to her and tell her that is you. Then find a seat in a dark corner and watch the show... Or get the F out of there before she figures out who you really are...
