Dundas West if full of hipster coffee - you'll see a few, then hit Dufferin, then see a few more... keep walking past Brock - it's worth it!
Cygnet is a wonderful find: Their coffee is smooth and perfectly brewed, their treats are fantastic (try their vegan cookie or their definitely-not-vegan-or-healthy-but-holy-smokes-delicious brownie), and the owners are friendly and caring. The shop is cute and modern without being pretentious, and in the summer you can people watch on their chairs along the sidewalk!
I have tried all the hipster spots along the area, and Cygnet is the only i return to. I suggest you come here at once :)
