Club Soya was located a block away from my hotel (Hotel10) during a recent stay in Montreal for business. On the two occasions where I dined alone I came to Club Soya. The first time I had the dragon maki and it was delicious! I only got a half order and it was very filling.
I could see this being a good spot for groups to share but the seating is a bit limited. They have bar spots in the window as well. Also their service was friendly and very fast. If I lived in Montreal, I would be a regular!
