It's kitschy as all get out, but there's no denying the goofy Polynesian pleasures of the Fairmont Hotel's tropical oasis. Drop in and join the crowds for an umbrella drink, a simulated thunderstorm and downpour, and a heavy dose of whimsy that escapes most San Francisco establishments. If you're on a budget, you'll definitely want to stop by for the weekday happy hour from 5 to 7pm, when you can stuff your face at the all-you-can-eat bar-grub buffet (chicken wings, chow mein, pot stickers) for $6 and the cost of one drink. Settle in and you'll catch live top-40s music after 8pm, when there's a $3 cover.
