You should start kinoing.
Your reports do not seem to include any physical touchy-feely stuff. That is not good. When you don't get physical, to the chick you become this non-sexually-threatening little thing, and they put a "friendzone" label all over you. Which is great if you want a new buddy for your commute.
Since you're here, it must be assumed you want to take her clothes off and perform the deed. To do so, kino is more important than coffee.
Sure, you can ask her to go grab a cup of coffee, but if there is no sexual vibe going on, it won't be any different from the subway station. Get the vibe going. Kino kino kino
