User friendly large gorgeous interior & terrific layout (can play angry birds seated at the bar while the barista crafts your beverage), courteous staff and more options.....your favorite Starbucks on steroids, what is not to like?
Will I seek it out? no. Will I miss it? not really (plain ole true north blonde is fine by me).
In Europe, I'd have no problems walking into a hole in the wall cafe or a convenience serving coffee, you know it's yummy. Only reason to pop into a Starbucks in Europe is for clean washrooms. In North America, coffee from even our fanciest artisanal coffee shops can taste like garbage or mediocre, hence my reliance on Starbucks here.
