There is no better place on the planet to start your day gastronomically speaking than "Swans" oyster bar in San Francisco. A dozen of the freshest oysters you'll ever eat, followed by a "Crab Cocktail" with Louie dressing on the side. Smuggle in some ice cold premium vodka of your choice and by God you'll be channeling Anthony Bourdain before your second dozen are shucked.
Get there early, because well before noon, the line is out the door and when the good stuff is gone - or 5:00 PM rolls around you're shit out of luck and you don't want to miss this place. Seriously it's that good.
