Glad you liked our city, although it has morphed into a hugely expensive place to live in the last five years (even more so than it was in the past)!
The decorative pu you saw is just that, and is not really something you want to drink.
As for the mini-tuos, they tend to be lower quality leaf: one is good for an entire pot, but I hope you're doing two rinses when drinking the fermented stuff!
There is young raw pu erh around, but not the variety that would be available in Guangzhou, for instance, which has China's largest tea market (and also a ton of 'fake' tea). Prices also tend to be much higher here. Fortunately we can buy raw cakes at Chinese prices online (often with free shipping), so it's not a bad place to be.
