The Tonga Room & Hurricane Bar at The Fairmont in San Francisco hosts an excellent Happy Hour. Not only is it in The Fairmont which is fun to look around in general, but this place has a lot of personality. Happy Hour is Wednesday through Friday from 5 p.m. to 7p.m. You can go there for a tropical, fun ambiance, island-themed drinks and Pacific Rim cuisine. The themed decor gives a little more pizazz to your average bar.
