If you are in the Bloor-Yorkville area and in a rush then Picnic is a fine fast food option. Toronto is finally adopting the Pret a Manger model! This branding is a bit more playful though.
Some people are saying that Picnic is overpriced but I don't think this point is totally fair; and I'm not just saying this given the area and the well-heeled crowd that it serves.
For example, I had a chickpea and quinoa salad with cucumbers, feta, herbs and dressing for $5.25. The volume was adequate to stave off hunger and the taste and quality was fresh.
