Okay, after reviewing this thread, I note that it has already been said here and there in some fashion, but for amplification here it goes.....
TIM HORTONS TIMBITS* FTW! 
^
*Timbits: ~3 cm diameter spheres (balls) that are made from the same ingredients as their normal donuts. I particularly enjoy their chocolate-glazed timbit
Note this is for those Tim Hortons located in Canada. I have not yet visited any of their locations State-side so I have nothing to compare to, though some posts near the start of this thread have stated that State-side Timmys tastes different. YMMV.
