Air Conditioned Internet Cafe

Try these suggestions from Dopplr, it's a start though there must be others. I imagine EXKI must be reasonably well air-conditioned, McDonalds too.

Apologies. A café with internet won't suffice? You don't have a laptop? How was I to know?

I'll leave it to you. Glad I tried to help.

It's been a long time back, but I think I've seen one in Midi station.
