When my SIL first came to SF from Chia, I took her to the Steinhart Aquarium as part of her inititation to the wonders of the City. Her first question was "Can we eat the fish?"
Well, you still can't eat the fish at the Academy of Sciences temporary new digs, but starting tomorrow you can eat the chocolate. In conjction with the traveling science exhibit "Chocolate: the Exhibition." Yes, there will be TASTINGS on Fridays and Saturdays, and chocolates from local artisans and other chocolate-related stuff will be on sale in the Academy store.
Ogle the fish while you are there too, but save your appetite for the chocolate.
