I have to say the cleanliness of Tim Hortons exceeds that of Dunkin Donuts. I was at the Dunkin a Donuts on Arsenol both at the Walmart and the regular and they had numerous flies and bees around their donuts granted it was in the fall but still. Although Dunkins coffee is good I notice the service is lacking in that department as well as their donuts. I think Tim Hortons has them beat with their donuts!
