Take away food? Is that an American phrase? I’ve never heard that before. I’ve heard of take out or pizza pick up.
People UK call it “take away,” here in the USA, we call it “take out.”
In the UK we use the single word takeaway to mean any restaurant with items “to go” or “take out”.
Post WWII, Chinese takeaways opened all over the UK and became very popular. My first visit to one, as a 10 year old in 1973, was to buy chips (fries) on a Sunday. At that time and into the late 80’s the British “chippy” - or fish and chip takeaway was prohibited from opening on a Sunday. I imagine the Victorian trading laws did not explicitly include Chinese restaurants.
I actually dislike Chinese food and had to wait until 1981 to have my first pizza - from a pizza takeaway restaurant.
