some years ago I was in a café and I heard the following conversation between the barman and a foreigner who wasn't a native speaker of English but spoke in English
The foreigner asked: "Where is the town centre?"
and the barman replied: " this is the town centre. IT IS ALL HERE"
The barman meant that the place is so small that the centre is concentrated in few square metres. Is the expression "IT IS ALL HERE" ok? How else would you say?
