Leslieville Cheese Market
Leslieville Cheese Market in the east end boasts that "everyone at Leslieville Cheese is a cheese expert". Check in with them in the fall about their cheese night school. Or try a Leslieville Cheese Board, 5 pieces of cheese totaling 1 kg. They even have a children's version, featuring a mix of mild cheeses ($35). (I guess you serve it with white grape juice.)
