Having lived abroad, including stays in Beijing, I can honestly say that Greenwich is home to a great and authentic Chinese restaurant, Hunan Gourmet on Putnam Ave. Having just bought a home in Greenwich I have been very pleased with my several meals I have already had there. Ask for it for Hunan style and spicy and you truly get what you ask for. People have suggested Panang Grill and Asiana Cafe to us which were ok, but for selection, food quality and service, Hunan Gourmet is the place. I make sure to bring my friends there for dinners and mai tais. Another thing, the specials are truly special. We had a dinner party at our house, on another occassion, for about 40 and the owners of the restaurant were very helpful and professional in helping us choose exactly what we were looking for. I do not think you would get that service anywhere else.
