<human>: Summarize the given text in a few sentences.

I haven't done the dating game in forever.  I may have posted a question similar before.  Either way, the girl who cuts my hair is awesome.  I've got her number, and friends on FB.  Outside of liking each other's posts or a very random text even more sparingly, we don't communicate except when I'm getting my haircut (which is once a month).  

She's cool, and I have no idea where she stands on dating or just about anything at all, but we've never talked on the phone (like I said, just very sporadic no-purpose texts, and they aren't common). 

Now, I'm not like head-over-heels or anything, but she's pretty cool and I'd definitely like to see if there's something worth pursuing.  How do I go about asking her to dinner or to grab a drink or something?  I've always adhered to "calling is better than texting" but since I haven't tried to date in a while I'm not sure if that rule still applies?  And if it does, would it apply here?  Having never spoken on the phone, is it ok to call?
<bot>: Wouldn't mind grabbing a bite or a drink with girl, but we've never spoken on the phone.  Is it okay to call her and ask if she'd be down?
