I met a girl at the gym the other day- we see each other there same time regularly, but this is the first time I've approached and introduced myself. We seemed to hit it off so I want see if she's be down to get a drink sometime.

Do you guys think its better for me to try and make an immediate plan (Hey, want to grab a drink tonight?) or just ask if she'd like to get a drink sometime and get her number? With seeing her everyday, not sure how it would play to just get her number and not organize anything then see her again every subsequent day.
