Late-nite coffee places with wifi?

So due to some wiring issues (a gift from the former owner of the house), we currently have no Internet or phone service at home.

We COULD go to Kinko's for free wifi, but that's rather sterile. And we'd rather support indie coffeehouses over Char$$.

So what are the nifty late-nite (like, open til midnight or later) wifi coffeeplaces in the LBC?
