1) I walked in this dingy little place and approached the counter. Glanced at the menu for a moment and was ready to order. The woman behind the counter seemed utterly indifferent to the fact that a customer was standing right in front of her. "Ahem... I'd like to order some food." I ordered, paid and sat down at one of the paltry tables. (This place obviously specializes in take-out.)
2) The surly guy who stood in the kitchen sneered, then began cooking my order. He later served it to me as if I were a convict in a prison cafeteria line.
3) The food itself, which was supposed to be *sesame* chicken but looked like sweet and sour (*red* sauce?), wasn't the worst Chinese I've ever had, but it was darn close.
That's three strikes. You're out, Beijing.
