The best restaurant in this part of town by a mile. It doesn't look like much from the street but the interior is cosy and comfortable if a bit on the loud side.
I have been half a dozen times and everything I have ever eaten there has been fantastic. Hands down the best gourmet hamburger in Toronto. Frequent changes to the menu and specials so there's always something new to try. Good, attentive and helpful staff.
You used to be able to just walk up and get a table except in real peak hours, but word is getting out about this place more and more. So reservations really are a must.
