I just came back from the most surreal experience I've had in China.
First, I ordered an eggplant sandwich, and it came out with no eggplant on it. Instead of taking it back and fixing it, they brought me out 3 slices of eggplant (for a sandwich cut into fours) about 15 minutes later. I also ordered a Diet Coke that didn't come for another 30 minutes when I realized it hadn't come and asked again.

Then the bill came, and all hell broke loose. They charged us 16 RMB for the french fries, but the menu said 12RMB. We asked the waiter, and he started saying that it was 16, so we asked to see the menu. After a delay in which we're guessing they tried to change the price on the menu bc there was a fresh indentation over the number but no ink, the waiter brought out the menu, which said 12 RMB. We started telling him that it said 12, so they should charge 12, when I saw the manager. I motioned him over, and WOW!

I told him that the menu said 12 RMB, but they were charging 16RMB. He said that the price changed, what is he supposed to do about it. I said that they should either charge us 12 or change the menu. He said that it was 16 kuai and asked why I had such a bad attitude (at this point he was yelling), which shocked me. I just looked at him, and my friends started talking. My friend said that we didn't have a bad attitude, but you should charge the same price as what's on the menu. The manager got really mad, said he had a bad attitude too, that he managed three great restaurants and knows what he's doing, but if we were going to be so rude about it, he would charge us 12 (which he didn't do). Then he went inside.

The waitress came out and started apologizing to us repeatedly. We were kind of in a haze. My friends live across the street and eat there several times a week. I usually go every weekend. We just told her that we wouldn't be back after that. Hearing that (because he was just inside the door), the manager walked back out and started yelling again something about we could go eat crap at Panino Teca but their restaurant was better or something... clearly anger issues that had nothing to do with us. No idea where that came from. The waiters rushed him back inside.

We paid the full bill (16 kuai for the fries) and left. We turned back around as we were walking away, and he was standing outside. He flipped us his middle finger to make sure we knew how he felt.

So, there ya go! We will NEVER be back!! I will look up what the other two restaurants he runs are, and I guarantee none of us will go there either!
