A bit delayed because of the holidays, but better late than never! Met some friends there for our Christmas brunch in Dec 2015. The restaurant was packed--definitely the hippest place to eat at Yorkdale. It was clean and our server kept checking on us regularly.
We sat near the kitchen. Washrooms are upstairs which may be cumbersome to get to but there is an accessible facility on the main level. I liked that you could order a regular or smaller sized portion. I ordered the rigitoni pomodoro with an arugula side salad. The food was ok; it was homemade and was tasty but didn't blow my hair back.
I am lactose-intolerant and while I was able to find something to eat (with some alterations), I hope that they will eventually have some lactose-free options. If I could purchase lactose-free cheese and other options at my local grocery store, I don't understand why restaurants can't.
Overall I had a good experience and I will go back if I'm in the area.
