Hong Kong has incredible Sichuan restaurants that are way better than what you'll find in most Western cities. Look for places that advertise 'authentic Sichuan' or 'Chongqing style' rather than generic 'Chinese food.'

Must-try dishes: mapo tofu (silky tofu in spicy bean sauce), dan dan noodles (sesame and chili oil noodles), and kung pao chicken (the real version with Sichuan peppercorns that make your mouth tingle). The numbness is called 'ma' and it's supposed to happen.

Red Chili Sichuan Restaurant in Causeway Bay and Chili Club in Tsim Sha Tsui are solid. Expect HK$200-300 per person for several dishes to share.
