i know not to drink out of the faucet in shanghai. I have heard that there are drinking water dispensers in the park. Those of you that have been to SDL, did you use those dispensers to refill your bottles, or did you stick to bottled water?
The drinking water dispensers are well labeled (in English).
In the summer, there were lines to get water from these dispensers
In general, you also need to be careful with ice in your drinks in China.
However, the ice in the drinks in SDL is safe ( I had it with no ill effects at all)
