I might suck at dating but I'm really good at meeting girls..
Firstly - what's your thing? Why are you attractive? Me, I'm fat and bald but I'm witty, very witty. So I go to places where my wit can be HEARD. If you're attractive, loud bars work. If you rely on your smarts and words, then pick quiet venues. Video stores, music stores, book stores, poetry readings, coffee shops.
If you thing is taht you're a great dancer, go to a dance hall. If your thing is that you're loaded, go to an expensive lounge and buy drinks for everyone, not just the girl you're into.
Group theory - we can go into this for hours but, to enter into a conversation with a group, talk to the guy of the group or the least attractive female, ignoring the female you're into. Let her earn your attention. Be witty, nice, charming to her friends and then slowly allow her in. Seriously works well, that's why I have no problem meeting girls. My problem is not screwing it up.
Also, do you live in a big city? THe laundromat is PERFECT for meeting girls. People sitting around, bored, waiting for their laundry.. I once had a friend wing with me - we played scrabble while doing our laundry and the girls found it really charming.
