Well, I would definitely suggest Tim Horton's, but of course I am biased because I am Canadian. There are just so many others but most of them (such as Starbucks) are overpriced and offer nothing exceptional. It also depends on your personal taste as well. So, what you can do is to try, try and try different ones and choose the one that leaves the best impression on your taste buds. Cheers!
