@altecz,
Did you use the date word anywhere along the line?

It may not matter this early on - or might make her uncomfortable to think of it as a date. Try and keep things comfortable and pleasant.
Get in touch with her later today - let her know again you had a great time, confirm you'd like to see her again and actually suggest something / ask her suggest something.
hi K - had a great time with you last night. I look forward to going out again. Same thing next week? or is there something else you'd like to get together to do? A

One of the questions we get here often (from men and women) is why someone hasn't been in touch to ask them out again after a coffee/meal/date - so they can't tell if someone really liked them or was just being polite.
