FREQUENTLY ENOUGH, Seattle gets dubbed a “city of neighborhoods.” It has a nice ring. So nice, in fact, that you can find the phrase also used to describe most any city in the U.S. But, hey, we can still identify. Plenty unites us as a city—coffee shops, verdant trees, sudden expanses of water. Yet few things so define how we live, from our homes to the restaurants we frequent, more than the neighborhoods where we land.
