Instead of meeting at a bar how about meeting at a cafe style place for coffee and a pastry, similar to what Roosh recommends for a first date in Day Bang? Instead of bouncing to the bar as the next stop go on a short walk and pitch the idea of going back to your place for a "real drink." Since she's under age she should jump at the chance of being able to drink with you.

From there run Tuth's first date recipe and add the notch.
