That would be Tim Horton's...Canadians are crazy for that particular coffee (our "crack" of coffee)-the rest of the "menu" is incidental to most. A visit to Tim Hortons is similar to McDonalds in this way, you always know what you are getting. Trust me on this, you wish you owned a Tim Hortons outlet in Canada or the northern U.S.=big moneymaker.
Regarding the comment of Swiss Chalet emulating Boston Market...I'm willing to bet that Swiss Chalet has been around a lot longer than BM. I don't think they are similar.
I'm not fond of SC either but you can get a ful sized meal for a reasonable price...and its fast. I think that is the draw...particulalrly with the older folk.
