Free admission. Very close to Portland Japanese Garden, recommend doing both of them.
$15 admission. Recommend the guided tour, and sometimes they have interesting events, like tea ceremony showcase.
They do tea flights! 4 bowls of loose-leaf tea (you pick all 4 from their very comprehensive menu) for you to sample. Bowls are large enough for two people to share one flight.
Salt & Straw does soft serve! It's in a little food court with some other shops (ramen, Mexican food, etc) and is open late.
