attempts to expand not successful? Not sure about that. Sure the first attempts (incl the Wendy's deal) weren't...but the current era of expansion in NY/NorthEast 'Cafe & Bake Shop' seems to have gone better...with Tim's learning/more financial power/proper ad marketing. It's become one of the small players in your everytown corner coffee shops. Just in a relatively small region. I mean, something helped attract BK to it other than the tax inversion.
My wife and I see ads for "Tim Horton's Cafe and Bake Shop" during NFL games on the US stations and it seems bizarre to us that they apparently felt Americans needed to have an explanation added to the name of the business.
