Met a girl at a business networking on Thursday Night. We had a pretty good conversation and she asked for my number. I only spoke with her for 15 mins before speaking with other people. I texted her after the event.

I want to ask her out for date (coffee or similar) but I am afraid she will think its a business conversation instead of date. Is there anyway to let her know this is a date instead of professional?

I know it's not perfect setup, but I would appreciate any tips on how to make it work.
