I like how they are listing businesses in the letterbox. Although, in that part of downtown Seattle there are 10 times more Starbucks than what they're showing in the video . . . and I'm not exaggerating.
But to your point, there are 2 Starbucks' directly on 1st; one in Pike Place and one just up from the ferry terminal.
I agree, though, that there are an inordinate number of SBUX-owned coffee shops downtown, especially once you factor in the SBCs.
