Whatever may be in season. A park, museum or something like that is fine. My gut feeling tells me that I should really just be kind of direct.
"All right, I was going to ask you if you wanted to grab a cup of coffee or something, but you do that all the time. So I was thinking of something completely opposite. So I've decided on a bar. But if that's no good, then we can compromise and have hot chocolate in the park."
Somehow, that's probably wrong because I've never really approached a girl with much success.
