My favorite was seeing the incredible flower shops run by the Hmong. The Hmong are a group of people from Laos, who, during the Vietnam war, came in large numbers as refugees to America. The Hmong were unsung heroes of the Vietnam War, with over 18,000 losing their lives in dangerous missions from the CIA in a special task force. As a result of the war, there are large Hmong communities across the country, with one of the largest in Northern California. Their flowers were brilliant, fresh, and endless.
Pike Place is famous for as a fishing market, and there are several fish and seafood shops. I'm not much for eating seafood, but it is an entertaining array of things to draw.
The "fish toss" is one of the main attractions of the market, with tourists lining up to take pictures as the sellers toss large fish back and forth.
