I was really looking forward to having a Tim Hortons' doughnut when I visited Toronto for a friend's wedding. I must say I was slightly disappointed.
I bought a chocolate doughnut and a regular croissant. The croissant was okay and tasted like any typical croissant I could get in the states. The doughnut was a disappointment. For me, a true doughnut has a fluffy center and slightly crispy crust. The doughnut I had more of a cake-like consistency.
Overall, I give it three stars. I plan on trying the other flavors on my next visit to hopefully raise the rating.
