Personally i feel ilke this starbucks trumps any other one i've been to around the gta. The service is friendly and fast here and the patio is super nice on a good weather.
It does get a little jam packed in here on weekends , so if you want a spot on the big table you might want to head there before 11AM on weekends to grab your spot. Otherwise, they'd be all taken for the next few hours for sure.
This starbucks also seem to have a few more kids around and is more family oriented than the other ones i've been to. I havent really come across really rowdy little kids yet, so I dont mind at all. its a good place to get some studying or work done.
