I have been to the Oakville location 2 times, and while I thought the food was delish, I didn't see what the craze was about. Basically, I thought it was a great brunch/lunch place for local Oakvillers, but I wouldn't make the drive out (as my friends wanted too).
And now, there is a Stoney's closer to home and I thought the food was really great! Especially the Catalunya pizza which is big and comes with chunky artichokes and veg. The pizza's here are good to share. I also like the concept of placing your order and then grabbing a table; they will come and bring the food. While waiting, you can get some nice drinks: a glass or bottle of wine and cool beers.
This location also has a pretty nice patio.
If ever I was in the West end and wanted something good to eat, but casual, I would totally recommend Stoney's.
