I didn't know about Jimmy's coffee until today and a quick Google search turned out numerous locations.
This one on queen west is a very simple place with a few bar stools. I think can only seat 10 at a time but most customers ordered to go anyways. There was a long line up. The menu is pretty simple with a few seasonal specialties. I had the s'more latte. The cups are smaller than a lot of coffee place but the flavour of the coffee was very pure and intense that you only need one to be satisfied.
I found this location interesting coz you can walk straight into a man's clothing store - frank and oaks, and at the end of the clothing store is a Barber Shop...
I will definitely be on the look out for Jimmy's coffee in the future
