Fine dining underwater

Tonight, boat out to SF's only underwater (yep, underwater) port hole-filled dining room featuring tons of nautifacts on the walls, a 40ft lighthouse you're free to wander through, and a slight sway (due to the floating island it sits on) and cash in on an exclusive-to-Thrillist 2-for-1 dinner special that'll be available every Wednesday in October and include French Country Chicken or Pan Seared Flat Iron Steak -- an obvious choice when, inevitably, the chicken goes on strike.
