If you've just flown in from a later time zone, get up early and go to Fisherman's Wharf to check out the sea lions that lounge like giant, stinking dogs, around Pier 39. (This, by the way, is the only thing you should do at Fisherman's Wharf, and only do it around dawn, before the tourists arrive.)

Afterward, head down Stockton St. into North Beach, the formerly Bohemian part of the city. Get yourself a serious breakfast at Mama's, which makes the best breakfast in town; it gets crowded on weekends, so get there early or expect to wait about half an hour. After breakfast, you won't feel like eating again for a days. Time to start walking off the food.
