It's the best Italian restaurant I've tried in Markham. I'd give it 4.5 stars if I could, but I can't and the last person gave a 5-star review.
The food here ranges from pretty good to amazing. The menu changes seasonally. Dishes cost on average $20-25 for a main course, but there are some costlier and cheaper ones. The pasta is fresh-made, and I usually end up ordering some kind of pasta. Vodka penne is great, and a special I tried once -- some kind of wild mushroom ravioli -- was incredible. I've had some nice fish there as well.
Atmosphere is fairly nice. It's an old house, lots of wood. Not very modern, nothing too fancy, but nice and warm. Sometimes they have live music, which I would rather do without.
Al Dente, another Italian place, is across the street. Folco's is far superior unless you need to rent a large space for a reception or something.
