Our server told us it first opened in Feb 2014. It reminded us of a combination of some of the large Italian chain restaurants in the USA.
Although the address is 382 Yonge Street, Unit #7. It is actually on the north side of Gerrard and you enter about 75 meters west of Yonge. You won't see it on Google Maps street view as it is part of the new Aura Condo building (tallest residential condo building in Canada).
The owners are www.sircorp.com which also own the two restaurants on either side of Scaddabush - Reds wine bar and Dukes.
Scaddabush is a large restaurant and looks like large groups are a primary target.
The pasta is made fresh daily on site (except for a few items like whole wheat). I am not a big fan of this type of pasta but it is nice once in a while. They offer a handmade mozzarella cheese appetizer which you can watch them make - we made it back to the kitchen just as they were finishing ours so we did not see the whole process - it did taste excellent and will order it again.
The wait staff are very good - although they seemed over qualified for their positions (i.e. lots of education).
We really liked that sircorp is not greedy and has wines starting at a reasonable $1 per ounce.
Overall if you have a party of two or a large group, you will enjoy yourself.
