I’ve been in Chengdu for almost a week now and I havent’t visited a lot of places, but I do know there’s a decent WiFi connection over at Peters Tex Mex Grill. The password is “peter”. It’s a good place where the waitresses speak a little bit of English. You can eat all sorts of European food and meet European people.
Should come in handy for the first few days visiting Chengdu if you have no clue on what to eat or how to speak Chinese.
