<human>: So I met this girl[21] in a training class at work and I've found that I really like her. We've spent some time together outside the office, though only ever in a group. She's invited me out with her friends both times and seemed legitimately excited when I accepted the invitation so I'm decently sure she's interested in spending time together. My issue at this point, is how to develop intimacy. I realize I need to ask her out one on one, but to what? What do people do for dates? I'm at a total loss and I've never done this before. I checked my cities website but didn't find anything either of us would be interested. Please help. Thanks.

Can you condense the text into a few key points?
<bot>: met a girl I want to ask out but I've never dated before and don't know what we could even do.
