On my last trip to SF Chinatown I bought a cheap shrinkwrap bing at a corner market I thought contained a CNNP wrapper. The wrapper was folded on the edges so I couldnt tell. I opened it last night and the edges said Yunnan XiShuangBanNa MengHai Xian NanNuo Shan. I should have paid more attention to the wrapper because NanNuo is in large Seal Script circled by smaller NanNuo Shan characters instead of the China character. It is a very mellow shu with larger leaves than the chopsuey CNNP. I would have stocked up at the price. This was the first shu I bought in retail that wasnt CNNP.

PS I can imagine some sheng eventually tasting like this but never looking like it.
