Jet lag can ruin all sorts of plans. While I was in San Francisco earlier this month and holed up at the luscious Taj Campton Place, I was too tired and jet lagged to stray very far from the hotel in search of a good meal. In the past, I've enjoyed dinner at Zuni, which I love, but this time I relied on the concierge's tips for where to eat close by. On our first night we tucked into Chinese food at the very casual and highly entertaining Hunan Homes  where the wait staff was cheerfully bonkers. It was just what we needed: gallons of strong black tea and simple, hearty Chinese food and amusing banter. The next day, after trekking up Lombard Street, we stopped in for lunch at the charming Nook wine bar where we tucked into huge ciabatta sandwiches and washed it down with a sake ginger cocktail (The New York Times recently ran a good story about San Francisco's lovely, and snobless, wine bars).  I also enjoyed E&O in Union Square, which reminded me of a bigger version of New York's Kelly and Ping. By this time, we were pretty much back to normal and ordered up a feast: duck imperial rolls with Thai basil and star anise, as well as smoked black cod and grilled salmon glazed with sweet mustard- and best of all, a short walk from the hotel.
