In August 2004 we decided, during our holidays in South Korea, to do a short trip to China where we visited some of the highlights.
At the end we came to the conclusion that, yes, Chinese food is the best of the world. Don't go to tourist restaurants (you will get the same stuff as at home) but try the many local restaurants even if they don't look very clean. The communication is no problem: Just look around what the others guests are eating, grab the waiter, and point to the dishes that please you. It can be very funny but we were never deceived.
