Pizaiolo because they rule, and because they have the most vegitarian options
Harvy's has a good vegi burger if I crave junk food
I love the Harvey's veggieburgers!
Montana's does/did have a fantastic one as well. I've never been a fan of the Lick's ones though.
Pizza... Ricci's at the corner of Weston & Langstaff in Woodbrige (Vaughan) is incredible. Whether it's pizza, pasta, panzarottis, sandwiches or salads, Ricci's can't be beat. Legit Italian food.
