By the time I boarded the plane yesterday late afternoon, I was quite full. As well as contented, happy, blissful and had a big smile on my face. The day started with breakfast at Tartine Manufactory with a friend, and lunch began with a big bowl of famous Zuni Café polenta with parmesan and a big dollop of marscapone studded with fresh cracked pepper. I actually did a bit of work in between those two meals, but when in San Francisco food almost always tops the list of memories of the trip. If/when you visit that fine city, put both on your dining list. The sensory experience of both eateries quite something and the food utterly divine.
