I've never heard of Toppers and have never even noticed the one in Collingwood.the website looks like a pizza pizza knock off....wonder if they are affilliated?...all the locations are northern towns.
Marconis Pizza has been around for years. they used to be in Marklandwoods plaza but had a fire years ago around this time of year. they then moved to Applewood plaza and now currently operate just south of Burnhamthorpe on the east side of Cawthra. there is also a good portuguese chicken joint in that plaza.
Milanos Pizza is another good place in the west end. Milanos is the place that blew up a couple of years ago. they are now located across the street from the old location in the strip plaza.... north side of bloor west of Kipling
and for the best pizza and italian sandwiches,can't forget Rocco's Plum tomato at Queensway/Park Lawn , Islington/Queensway , Bloor/Bathurst
I highly reccommend the Roccos Rustica club sandwhich with Roccos house salad. you can even have a pasta side dish instead of salad for under 10 bucks.
Roccos rocks!
