I am not sure how to do this...sober at least.

Usually I pass by a few women quickly so i can't comment too much on surroundings...which seems to be a popular idea.

Maybe just a...

"Hey you are gorgeous, I'm so and so..." "Do you have a boyfriend...?" Closed by...."Would you like to grab coffee sometime?"

Another option is asking a question.

I'm in a busy urban area and I could ask a question about directions...and then get into the routine...but I'm worried this will be obvious.

Any thoughts are much appreciated, thank you.
