You can tell me it's touristy, and I will agree, but I had such a fantastic time doing the night market food tour with UnTour Shanghai. I speak no Chinese and was with my husband (after a few days working) and it was so wonderful to have this great food given to us without having to figure out what we were eating (not a problem, actually, I will eat anything that is presented to me ;-) I still am not really sure what we ate, but it was good, and I was happy. But I have an unreasonable love for street food....
