Ok, I really wanted to read through the chocolate exhibit, learn its history, enjoy the nature of its mixed heritage, but my four year old son just zoomed through it and asked for the piece of chocolate he was promised (special promotion for the day). So I didn't get to enjoy it that much, but maybe if you go without kids, you'll be more entertained. He bluntly stated, "this is boring." He was much more into the penguins, and other marine creatures available for observation. The temporary Howard St. location is ok, but I prefer the Golden Gate location. This is much too small for the price, and my son got bored pretty easily, after he saw all the animals.
