Cuisine X was opened by a lady called Xu Yuan (hope I have the spelling right). She makes a lot of her own sauces and even grows produce in her plot in Yuen Long, which was, until recently, open as a private kitchen. she also had a catering/take-out like business in Sheung Wan. The Yuen Long outlet has since closed, but I'm not sure about the Sheung Wan take-out outlet.
Recently she's opened a restaurant on Ship St in Wanchai called Yin Yang. It's pretty much been the talk of the town - it helps that it's housed in a heritage building. Last I checked, if you wan a weekend dinner booking, it's about 2 month's wait. I'm going early next month - i'll report back - hope it lives up to the hype.
Is this a Cantonese food private kitchen? I live in Los Angeles, and recently saw a program on TV about a private kitchen in HK where the chef makes very traditional Cantonese dishes. When I did some googling, I found Palace Kitchen in Happy Valley--does anyone know this place? I couldn't find anything on it here.
