I am good acquaintances with a Chinese girl at a restaurant I dine in every week. I've know her for over a year, and I have every confidence she likes me. I would like to know what the best way to approach her might be. I actually don't have her phone number, so I should probably start there. In the past, I would usually just give an American girl my number, and she would call me later at her convenience. Or would it be preferable to ask my Chinese friend for her number? I will not ask her out while she's working, so I know it's kind of lame I might have to do it over a phone call, but I think it might be embarrassing for her in that situation. I'm also wondering if I should behave a certain way for her benefit while we're out together, seeing how I don't know anything about Chinese dating etiquette.
