The density of Vietnamese restaurants in Seattle is unreal. One of the most renowned is Than Brothers, a local chain serving up the best bowls of pho. There are at least 45 restaurants in Seattle with pho in their name, and even more Vietnamese restaurants that serve it. (And FYI, it's pronounced "fuh," not "foh.")
Don't even think about suggesting that Starbucks is the coffee of Seattle. (Or Seattle's Best, for that matter.) There's a little espresso drive-thru just about everywhere you turn. Or, if you're looking for a place to sit, check out Caffe Vita, Victrola, Caffe Ladro, or Vivace.
