Adding a bit of Willy Wonka to Fremont's atypical street life is this chocolate factory on the site of the old Redhook Brewery (now moved to Woodinville, WA). The chocolate micro-producer makes organic chocolate and the detailed factory experience is both witty and interesting (if you don't mind donning the obligatory hairnet). And, yes, there are tastings!
Factory experiences last one hour and are offered daily. Tour times vary, but tours generally run semi-regularly between 10:30am and 4:30pm. Visit the website for a detailed calendar of tour dates. Reservations recommended.
