Brings back wonderful memories. At about the same time you were there in the city, I lived just around the corner (Taylor and Washington) from the trolley barn and would go the few down the hill to Chinatown and look for the restaurants with the longest lines of orientals...hmmm, mighty good eats.
One thing I'll say about San Francisco - it's got flavor; something that my home area of Los Angeles had not one iota of.
