This rating is for the food itself and not the wait, the prices, the lack of seating or any other inconvenience. If the review were based on all of that, I would give it a 4. The staff will not shower you with love. They are too busy preparing and delivering great food.
To call the product that Osterio Berto sells a "wrap" is doing it an injustice. It's called a wrap because the ingredients are held together in a tortilla. But it's unlike any wrap you've had before. The location is on the North West quadrant of Highway 7 and 27, is easy to get to and there's lots of parking.
The main choices of steak or chicken are available as a 2 Tower (8") or a 3 Tower (12") and can be accompanied with a salad, which is also excellent! The "Tower" description relates to the way the wrap is served (i.e. cut into 3 pieces and placed standing in the dish as "towers"). The ingredients are simple and fresh and it all just works together beautifully.
The only downside of this place is its popularity and the fact that great food is not fast food. At lunch time it may be hard to find a seat and the wait will be about 20 minutes (based on my one visit), however the end result is worth the wait. The prices are very reasonable however a 3 tower wrap will cost about $15.00 with taxes.
Next time I will go after the lunch rush and take my time with the wrap and hopefully have time to finish it off with a nice coffee and a desert. Great place and hope they open one in Mississauga.
