I have no connection to the app, but an iPhone app I found indispensable is Shanghai Taxi Guide. It has an amazing list of places broken down by type (restaurant, bar, shopping, services) and when you click on the place you want, an contact card comes up with phone and address. On that page is a button to switch it to a taxi card that you can show your driver, No need to carry around pieces of paper to show a taxi driver. If he still doesn’t know where the place is, you can just click on the phone number and then hand over the phone.
Great app.
Wish I could join you all there. I know you’ll have a great time.
