I'm planning a weekend trip in SF from LA. By the time we arrive at our hotel in Union Square (right next to the Powell St. BART station) on Friday night, we would have been in the car for 7 hours. What scrumptious eats are open late and within good walking distance? I want something that'll hit the spot after a long tiring drive.. maybe even a lounge place...that'll introduce all of us to SF and warm us up for the rest of the weekend. Thanks!!
