In answer to my listing of great American neighborhoods, some of you have disputed North Beach. I am not arguing. I do like to eat at the restaurants and drink in the bars and just walk around — but I don’t do it much, anymore. I mostly stay in the East Bay. So here’s what I want to know. In what sense, has North Beach fallen down. And please name some great San Francisco neighborhoods, ones that can stand up to, say, Greenwich Village which is great. Steve kindly and helpfully made a case for Bernal Heights.
