Not stuck, just looking for optimization. "How do you feel about joining me on my romantic balcony and sharing a bottle?" has the advantage of presenting it as a question, shows that I care about what she thinks, and adds the intimacy value of "sharing" it. You don't necessarily share a bottle of whiskey so it's kind of odd to re phrase it in that way (I've tried and usually the reaction is shock "a whole bottle?!") and have the same impact. Also since she's into hard liquor that indicates that she's a different type of girl so I thought possibly there is a more suggestive, flirtatious way of presenting it that is more optimal and already put through its rigors by someone like you or J Anthony.
