We were accompanying a friend here for business in Toronto near the airport.
Best calamari we've had. Ever. Anywhere. Very light batter. Perfectly cooked. Not rubbery at all. My partner loved this. And he doesn't even like calamari!
Definitely order it. 10/10+
Maple Arctic char was good 8/10. Well-cooked, nice accompanying mushrooms, heirloom carrots, etc.
Halibut was only ok. A bit dry. 6-7/10
Paella also ok. Not super-authentic, but decent. 7/10.
Tomato-red pepper soup. Fairly yummy, light. 8/10
Crab cake appetizers 6/10. Ok taste (actually a little tasteless), a bit too mushy, not crispy enough in the outside.
Dessert?
We ordered tiramisu (more whipped cream than usual , but tasted light and good), bread pudding ("alright, not extraordinary") and an Irish coffee (7/10).
Overall? Decent restaurant at Sheraton hotel by the airport. Convenient if you're in the area. We've also been to Chop Steakhouse in the same hotel when family was in town for a quick layover (which is more crowded)...more standard steak joint. I prefer Olio. Not extraordinary (apart from the calamari), but convenient location.
A bit pricey (~$20-30/entree), but that's rather typical for all these hotel restaurants by the airport ( for the better ones anyway).
Service was fairly attentive (although place was pretty empty when we visited at 8 pm...although its adjacent bar section was pretty crowded).
