"This historic bar inside the Clift Royal Sonesta Hotel has been open since the '30s, when waiters in white tuxedoes served the drinks (indeed, the Redwood Room's conservative dress code made it an important battleground for clashes between San Francisco's old guard and the long-haired kids of the '60s). The art-deco style space underwent a complete restoration in the early 2000s, bringing the redwood paneling on the walls and the deep bar, which was rumored to have been built from just one redwood tree, back to their former glory. The vibe here can get a little clubby at night, so we like to stop by in the early evening for pre-dinner drinks."
