Farallon is a Union Square institution known for decadent prix-fixe menus and playing host to special occasion diners. For a less formal experience that serves up equally delicious food, try out the Oyster Bar. The laid-back atmosphere is great for a light dinner or extravagant happy hour, complete with caviar, champagne, and a friendly after-work crowd. The seafood is fresh and flavorful: oysters, shellfish, lobster claws, dungeness crab, cherrystone clams...we couldn't help going back for more (and more, and more). If you can't decide among the robust menu options, chat up the chef behind the raw bar, who's knowledgable, friendly, and can anticipate what your tastebuds are craving.
