Picnic is similar to the Pret a Manger style of store that you see in many European cities. There is a wall full of small, healthy, bite sized food options (i.e. green macha chia pudding, pomegranate and spinach salads). At the main counter you can order pasteries or something from the juice bar.
This is a welcome sight in the bleak, healthy food deficient underground of Toronto. It's ten steps up from the stale pizza, hard chicken, and sucpicious sushi from the food court down the hall.
For my visit, I mentioned to the person at the main counter that it was my first visit. He gave me a gluten free cookie to celebrate!
Awesome place.
