Tim's (IMHO) is an inferior blend to McDonalds coffee (which is way, way better in my opinion...)
Starbucks can be really good.
At some locations, Starbucks will make you a pour over - if this is the case in your area, go for it.
Tim Horton's products, like their doughnuts and bagels are sad indeed.
The doughnuts are manufactured in Ontario, Canada and "reconstituted" or re-heated at their destination Tim's across Canada.
Tim's products, quite arguably, are the worst in Canada.
Trust me - I know. I have been Coast to coast at Tim Horton's in most of the Canadian provinces.
Any decent bakery can kick the stuffing out of Tim Horton's.
Their doughnuts and coffee are miserable - give me the jitters and a stomach ache as well.
