If you are in a city, arrange the date/pre meeting near her place, then just ask to use the bathroom.
Ask them something about their place that is unique (like, "have any cool artwork on the walls?") really, just anything that you can then fall back on and use as a way to ask to go to their place. "Hey, want to get out of here, btw, I want to see that painting you mentioned!" Nothing is guaranteed as someone mentioned, but if you want to go back to their place, the most effective way for me has been to set it up by finding out about their place and then using what I found out as an excuse.
Sorry, did not get the bathroom part?
Otherwise the artwork and "reverse nearby-home date " (

) is a pretty good idea ! (extensions on that, that just came to my mind :

girl plays an instrument,

likes a TV series and has some DVDs at home,

has a pet etc etc etc) as all it is in the end is an EXCUSE to get there. The girl will KNOW it is just an excuse and may (or may not) be CONFIDENT that she can turn you down if she wants once there (and then of course it is down to you to make her not want it, turning you down, that is).
So, good idea, I think in basic cases, "technique" or automatic responses to annoying situations can be very effective, because someone somewhere has already put some good thought/effort into it..
