The view of Toronto and Lake Ontario has been breathtaking. As the name suggests, the restaurant rotates 360 degrees. It is very subtle. You don't even feel the revolving movements.
I don't think the food was particularly good or bad but it wasn't really memorable; perhaps because I was captivated by the beautiful view of the city. Food may have improved as my review is not up to date. The server was attentive and friendly. You can even purchase a souvenir photo of your group dining inside the restaurant.
Price-wise, if you want to go up to the Observation Deck, it may be about the same amount of money to spend on admission plus some food elsewhere versus having access to the Deck by eating at this restaurant; especially for lunch.
