The hotel is diagonally across from a huge mall but I shall save shopping for later :-) elimloth (I can't get @' tags right in email posts) came by and we walked across town to find a way out to the lake. We ended up on a bench overlooking a little marina where I saw a fibreglass owl spinning in the rigging! Lovely views onto the lake and the splash of water and diving swooping birds like swifts but with red waistcoat fronts. They were there to thin out the clouds of insects... Local insect bites don't compete with whatever bit my knee in London, which is still alarmigly red (far better than scary red this morning though!).
We walked back through a park with a lovely water feature: a stream runs in a wide circular sweep down lots of little cascades (alternating a cascade and a footbridge) to a reflecting pool with a curtain of water sheeting off the side. There's a more traditional fountain at the top: I also saw a lovely water sculpture outside the bank with fountain heads like flowers with water gushing out in curving sheets and a pretty water sculpture on a deck by the lake.
Thanks to elimloth for a delicious dinner at PF Changs: shanghai street dumplings are a steamed bun with a crisped base and sweet dipping sauace (or the dipping sauce they mix to your taste at the table). Then we had mu shu pork (because I can't get it back home) and ground chicken with egg plant (the ground chicken pieces are about peanut sized). Yum. And sleep now!
