House of Hunan is located on 2 Townsend in the neighborhood call Mission Bay. It is part of an Apartment/Condo Complex, so it is hidden away from the main street call Embarcader. This restaurant serves schezuan and hunan cuisines in Hong Kong style. The Hong Kong style that they use is called "Poe Wok," which is recognized as a skill to make food taste great, where as some restaurants in San Francisco uses "Surng Fei" are not as good.
