It may sound crazy, but try with natural game.
If you see a girl on the street that you find hot, just go to her and tell her what you think: "hey. I think you are cute and i just have to at least know your name." then take it from there like: where are you going, where have you been- then tell her something about you that connects with her answer, with that you will lead the convo and then you can basically ask anything.
"where are you going-there and there-OMG i love that place, i did this and that with my friends there. So what do you like to do in your free time?"- you get the idea
Be funny, have a smile on your face, dont be too serious.
Or you can go more indirect, like asking for the time or directions and then asking her to show you the way if she have time or to help you choose clothes. Or ask a random stranger that you need womens help on choosing a gift for your sister/aunt/...
Hope thats something to get you started
