I got a tip about a new online database that compares the number of Starbucks stores with other cafes within a specific postal code. Delocator.net has been around for a while but is US only. But now we have Delocator.ca that lets you do the same in Canada.

A couple of days ago it was missing lots of cafes, but I just checked and the list is growing. You can help too by adding your favourite cafe. And then go write a review at Cafe Geek.
