We took my mom to do the tourist thing in SF today: we took the Cal Train from Palo Alto into SF, and then the Muni buses (which take forever) to Fisherman’s Wharf (overrated), the Exploratorium (San Fran’s best-rated museum), and a Blue and Gold Bay Cruise (there were so many people we could barely see anything, and the noise from the engine drowned out the audio presentation for a good portion of the tour). We ate lunch at the Expo Family Restaurant (no website), and at the Rain Forest Cafe (which was quite an adventure: the food was decent, but the atmosphere was excellent)!
We also had a chance to drop by Ghirardelli Square (yes, like the chocolate company). It’s a mall area, but they do prominently feature chocolate! Very tasty.
