There's pros and cons in everything.
Generally, we like girls who drink when we are out for a one night stand, as that loosens up your inhibitions, and the sober woman generally isn't going to be game for such.
For relationships, women who drink are generally trouble. Girls nights out will be at the bar with her friends and it makes the likeliness she'll step out 10xs greater. Also that crazy gene women possess, drinking makes it 10xs more annoying when the party stops and you have to deal with her later.
