I visited San Francisco for the first time last weekend. Definitely one of my favorite US cities and very cozy. Yes, I found it to be cozy. Must have had something to do with the fresh clam chowder in a sourdough bowl and the mint chocolate sundae in a waffle bowl from Ghiardelli Square. Definitely. My favorite part of the day was when we went to a lesser-known overlook to see the Golden Gate Bridge. The light was absolutely stunning as the sun went down.
My list of "I must come back here" cities is getting rather long.
