We arrived, got sat, and ordered at 5:00. Our orders were only relatively small.
By 5:40, we hadn't so much as being looked at, or our drinks refilled, while everyone else (or, at least all those who could speak Chinese) had being served.
At 6:00, I snatched a waitress, and asked her to check where our meal was. She said 'yes', and then just... Completely ignored us again. Didn't check. Didn't go to the kitchen. Didn't come back. Grabbed a waiter; Process repeats. We're the only ones not eating.
At 6:20, we have to get to the concert ASAP, and we stand up and explain we have to go now. We get told they were JUST about to start cooking our meal. (My mother thinks this was complete bullshit, and that they never planned to serve us at all.)
Luckily, there was one of those handy, cheap bakerys around the corner, so I rushed and grabbed a cream-filled roll to snack on before we went. My poor mother, and friends, didn't get to eat at all.
