The falafels are amazing. Seriously.
The muffins are too. Screw Tim Horton's and Richtree, you need a peach muffin from Mystic. The place looks like a dive but the muffins are truly gourmet.
The apple cake is really unique and fantastic. It's a soft, fluffy, spiced slab cake with a topping of apple slices and crunchy melted brown sugar. For years as a student in Toronto heading out of town for long weekends on the Coach Canada bus, I rode past this place and saw the signs for the World's Best Apple Cake. Now I work down the street from Mystic and I believe it.
I'm not sure why it's marked as wheelchair accessible. There's a step up through a narrow door to get in.
