As the fate of the Tonga Room, San Francisco's classic tiki bar, hangs in the balance, one of the most vocal advocates for saving it is Martin Cate, cofounder of Alameda's Forbidden Island Tiki Lounge and now proprietor of Smuggler's Cove. While there are no simulated thunderstorms at Cate's new hot spot, he's definitely shaking up the city's cocktail scene with his geeky dedication to premium rums, tropical juices, and other tiki-era ingredients. The Hayes Valley hideway has an immersive decor — ropes, wood planks, and waterfalls — but it doesn't feel like an overwrought version of Pirates of the Caribbean. And Cate has designed a set of education programs for the public, who can drink their way up the three levels of the Cove's "Rumbustion Society."
