Farallon
450 Post St., Union Square
In a city that's known for great seafood, Farallon has been a go-to spot for fish and shellfish for almost 20 years now. It's sort of an old-school joint at this point, but the oyster menu is miles-long, and the dinner options always include a great lobster dish and excellent grilled fish. Décor-wise, they’re famous for the jellyfish lounge, where jellyfish lamps hang from the ceiling and the mezzanine level itself is shaped like the creature. While it;s a little bit over-the-top, you have to appreciate the lengths they took to make the space unique and special. The private rooms here are decorated in the same fantastical style, and they've been around long enough to appreciate the value of having an event planner on staff, which always makes things easier.
