Well, Wicked has been playing for a while, and I heard that it’s pretty good if you like musicals.
It really depends on what you like, because SF has soo much to offer.
I can tell you some of my personal favorites, these would be things that I would do if I were to take people around from out of town (and have before!): go to Clarion Alley in the mission and look out all of the murals, than take a walk down 24th St. and look at more murals. Walk to the very end, where I sit on the top of Potrero Garden and look at over the whole city. I would pick up a burrito at El Metate on 23rd and Bryant, but there are tons of good taquerias.
Go over to North Beach and go to House of Nanking for some good Chinese food or Tomaso’s for excellent pizza. Check out the beat bars around there.
Stroll around Land’s End and check out the Legion of Honor (where some of Vertigo was shot).
Last but not least, walk through Golden Gate Park on a Sunday…
