Don't know what the liquor regs are in your state, but in NY City only liquor stores may sell wine and spirits. In those liquor stores in Chinatown, you can find Chinese liquors. Japanese sake and plum wine can be found almost anywhere.
Haven't had a Chinese one in years. Pretty herbal drink it was, too -- on the order (very broadly) of our Benedictine or some digestive, but of course using earthy Chinese herbs.
