As the previous reviewer Eva C wrote this is indeed a hidden gem. If you come early you will see a short line of people or a bunch of happy costumers drinking great coffee and loving every second of it.
The made a wonderful latte and the croissant I ate was just perfect. The prices are somewhere between inexpensive and moderate but the quality as I wrote is superb. Mile end is filled with great coffee shops this one I believe is in the top 10% if you are nearby just go for it
