Pike Place Market
Opened August 17, 1907 when eight farmers sold produce from wagon backs to 10,000 people furious about rising food prices. Now it's nine acres of chaos—fish flying through air at Pike Place Fish, Rachel the 550-pound bronze pig collecting $6,000-$9,000 annually for social services, the original Starbucks (which purists will tell you is a tourist trap), and that disgusting Gum Wall. Fish throwing started for practical reasons decades ago: expediting sales by tossing catch from front counter to back. Tourists made it performance art.
Pro tip: Arrive before 10am to beat crowds. The lower levels hide the best small shops.
