My friend and I are having a girls getaway and headed to Sonoma Valley in March with our first day/night stay in San Francisco. We will arrive in San Francisco around 9:30 am, March 8th(if no flight delays) and will check in for 1 night at Sheraton Fisherman's Wharf, leaving for Sonoma the next morining. I have visited San Francisco in 2003 but my friend has never been. What are your suggestions for must see? Alcatraz is not an option due to time restriction. We are not into riding bikes but we are prepared for lots of walking. Maybe suggestions on bruch, dinner with a view (casual restaurant), casual bar atmosphere and maybe next day breakfast? I rember eating breakfast at a place called "Mammas" for breakfast on my previous trip and it was really good. Is there a better option close to our hotel for breakfast?
