Went to Tenon for birthday dinner Friday night because we were looking for a vegetarian/vegan place and heard from friends that this was the place to be.
Service was quick and friendly. The restaurant wasn't too busy, but we did make reservations just in case.
We had the a la carte menu instead of the ayce. We ordered a couple dishes like the special dragon rolls and mango rolls which were pretty good. Also had the agadashi tofu which was disappointing to say the least as it was dry and tasteless. We also ordered thai style noodle which was essentially udon noodles in sweet red colored sauce with basil. Also ordered stone pot mixed vegetables with 'chicken' tasted pretty good, the 'chicken' which was gluten was ok but still doesn't really taste like chicken.
All in all the place was not bad. If anyone is looking for vegetation/vegan in Markham then you should try it out.
