They have reservations for 2 available on Friday night for an upscale awesome vegetarian dinner.
Americano (across the street from the Ferry Building where Slanted Door is) is a nice semi-swanky place to grab a cocktail, especially out on the patio if it's a nice day. Pier 23 down the street is a more casual place to grab beers on a nice sunny day.
Plenty of other great bar suggestions in this thread. Gimme a call when you're here.
