During my work week, it's about equidistant for me to go to either this Starbucks, or the one at Yonge & College - I now pretty much pick this one over the other when i'm even considering a Starbucks in the first place.
It's roomier in the queueing area, it's on a quieter street, the staff are super nice pretty much all the time, and helpful to boot. It's a Starbucks, so quality-wise and product-wise you know what to expect when you walk in - but it's a pretty well-rounded location. I only get to-go, but they do have a decent seating arrangement inside and small patio-like area out front.
If I fancy a froofy drink or a coffee that won't taste like dirt and I don't have the time to go to any of the indie places vaguely near my work, this Starbucks is my BFF. Taking the taste/quality of the product into account, it's a far better option that almost all of what's in the College Park block, and solidly deserving of the 3 stars.
