Pierre's Poutine in Guelph
I really enjoy this place. Poutine is great, although a bit pricey. A chef friend from Montreal was visiting and was very sceptical of the place. Once he tried it, he said that it was similar to what he was used to in Montreal. We spoke with the owner, who was very nice and originally from Quebec, and apparently they import their cheese from Quebec.
It is worth a try!
