My loyalties aren't so much to Tim's in general, but to the one specifically near my house in Coventry. The service is ridiculously quick, and the staff are super friendly. Couldn't care less about any other Tim's, but man I love the one by my place.
In terms of expansion, forget the US. Go to South Korea. They absolutely adore coffee out there. No exaggeration, in some of the trendier areas in Seoul, there are probably six different coffee houses on a single block on average. And they're all super busy all the time. They all serve pricey Starbucks-like coffee too. I feel like Koreans would go crazy over a cheap coffee option.
