I like this Starbucks because it's not always super busy and because it's an 'island starbucks'. With no walls and no doors, you can find it right in the middle of the 2nd floor of The Scotia Centre, in between The Bay and Rexall Drugs.
The staff is nice and the drinks are as good as always.
I find most downtown Starbucks are super congested and crowded, so this one is refreshingly different. If you're in the mood for a java and you're in the core area, head on by!
