Interesting idea and it works in B&W, but the photo's main focal point for me is the man having his coffee and I find myself distracted by the second sign and the reflections.
Good subject and composition, but I think that even though SBs started in America, it's now world-wide and probably not a strong enough "spirit" anymore--I could be wrong.
I like the shot. The hint of movement works. The B&W is perfect. The country is a mystery as there are Starbucks in almost every country in the world now. Sorry, slightly DNMC IMO.
