He goes to a barber downtown. (Merriam-Webster’s)
Does a barber mean a person or a shop?
Answer
It could refer to either a person or a shop, but probably a person. However, nearly all barbers work in barber shops. So, in effect, the person is going to go to a barber (person) who works in a barber shop (place) that is located downtown.
