チャーグリルって何ですか？

Customer: Excuse me, I ordered rare steak. But my steak is burned.
Me: Hmm, what's wrong with your steak?
Customer: Look at this. There it is burnt.
Me: Oh, our steak is char grilled steak. It's always charred on the outside.
Customer: What is char grilled?
Me: Char grilled means flame grilled. It is grilled over an open flame to quickly sear in the natural juices and flavour.
Customer: Oh, really?
Customer: (Customer cuts her steak.)
Customer: Oh, yes. This is rare steak. Is this normal steak in Australia? 
Me: Yes, it's the normal way to cook steak. The surface of the steak gets a little bit burned but it gets the smokey charred flavour.
Customer: Hmm, ok, I'll try it. Thank you.
Me: I hope you like it.
