<human>: Could you distill the essence of the text into 1-3 sentences?

I don't know if this was really a date so I need advice. We have a good mutual friend but I only met her one time, over a year ago, and she recently messaged me to say we should hang out sometime soon and gave me her number. So I texted her and we went to dinner. 

Nice place, good food. Good beer! We both dressed reasonably well. Stayed for like three hours, hugged goodbye. Only thing was, I didn't pay for it, didn't really get a chance. (Which TBH is ok b/c if it wasn't a date then I would rather save $20 lol.)

Today, I figured I would text her saying it was good to see her and we need to hang out more often.

But I don't know if that comes across weird if it wasn't a date. And if it was a date, maybe the words "hang out" are not good?

Obviously I need guidance haha.
<bot>: Went to dinner with a friend of a friend. Don't know if it was a date. Should I send the "had a good time" text today?
