"κέντρο" can mean "downtown", but it can also mean "in the middle"
You're right! Corrected :)
Right. This should be clarified for the context, and updated to be "Our friend is downtown. / Our friend is in centre city."
"downtown" is already included.
I'm curious where people say "Our friend is in centre city". I've only heard it as "Our friend is in the city centre." Could you please give a geographical reference?
also, a common way to say this in British English is "our friend is in town"
(This is also commonly heard on the west side of the Atlantic.)
My answer: "Our friend is in the city center." was not accepted.
It has been added. Thank you
