The Tonga Room, Fairmont Hotel in San Francisco, CA

 The Tonga Room offers great drinks, big portions and some Polynesian fun.  The tables surround a lake and there are "rain showers" from time-to-time.  I had a classic mai tai that was fabulous.  They offer zero-proof cocktails, as well.  The menu is small and focused on poke, wok-fried Polynesia food and pupu snacks.  

I had the tiki noodles with chicken and it was very good.  The portion was big enough for lunch the next day.  

This is a really fun spot to take friends!  There is an entrance on California Street and there is another entrance from the lobby of the Fairmont Hotel via the same elevator that leads to the gym.  Reservations are necessary!  The place is packed on Friday, Saturday and Sunday nights.
