The terrace at Honi Honi is a tropical-island oasis that literally rises above the mayhem of Lan Kwai Fung. It was Hong Kong's first tiki bar and although no longer the only one, it's still the best, with a decent happy hour (cocktails from HK$40, unusual for Hong Kong's top bars), classy '70s furniture and excellent cocktails with fresh fruit.
Also look out for the Uncensored Cabaret – an anything-goes gathering of local acts one Sunday a month.
