It's Pizzaville's 25th anniversary, and they're bringing back some of those old ads of theirs for people to vote on. Kind of a neat idea, and definitely takes me back!

I like Mike's ideas...if you wanna show off AUTENTIC Toronto, as weird as it sounds, I would avoid a lot of the more touristy things - CN Tower, Casa Loma, etc. (Though a Jays game in the summer might be nice).
