The best restaurants serving Greek food in Childs Hill Barnet London

Food is ok, ambiance is chill and kids friendly, however the waitres could learn hospitality mannerism. We ordered grapefruit juice and she served a drink with a lemon flavoured label, we pointed it out, and she replied “ can’t you read arabic or hebrew? It’s says grapefruit in there!” So rude, I’m hoping this feedback is helpful for the management.
