Brushing aside the irony that you already need to be online before you can use an Internet café locator; cybercafés.com is a good starting point for staying online when you're on the road.
The brains behind cybercafés.com have decided to keep things simple; and that's the websites greatest strength. You plug in the area where you are looking for an Internet café(via a clickable map or search box) and cybercafés.com comes up with the answers. Their database is ever-expanding and currently holds more than 4,200 Internet cafes spread over 140 countries.
Besides providing physical and online addresses you'll also get opening hours and sometimes an indication of cost. And that's it; there are no unnecessary bells or whistles. It's then left up to you to deal with the vagaries of the local telephone system.
