It does sound like he was into you and it's worth calling him. Once. That way, he has your number, knows you're interested, and you can both take it from there. It's a good way of knowing how much effort he's willing to put forth if you guys end up dating, and you're letting him know that you're assertive and interested, which are two positives!
And if you do end up meeting up, I'd suggest no bars for the first few dates. Something low key, like coffee, lunch, whatever.
I have a friend who always seems to be in a similar situation (not exactly, but somewhat close) and her mistake is that she always calls more than once and then just looks like a stalker. At some point she loses her dignity and then just doesn't know how to act, and it's sad because she's so totally not like that in other situations at all. I'm no advocate of playing games or "hard to get" or anything, but I think it's easy enough to get across that you're interested with one phone call.
Anyway, good luck! I was going to comment on the whole "thrill of the chase" thing, but I don't have much experience dating men. Although I don't know how much of a gender thing it is, men are notorious for it for whatever reason, but I think women can like the "chase" too (or maybe the equivalent is the "I can change him" phenomenon, which is maybe a different thing altogether, but somehow related). My girlfriend definitely had the "chase" thing with me and apparently I provided a challenge without even realizing it. Who knew?
