Catsu Curry, one of my favourite dishes. Every year at Bestival I eat that most days, the dude that owns the stall even knows me by name. I know that's not Chinese, but it's take away food, all the same imo.
I once went to a place called Karahi King in NW London and they served seekh kebab curry. It was fcking delicious tbf along with a big jar of mango lassi to wash it down.... but I was mash up at the time.
