dantheman - you obviously haven't seen the Victoria Wood/Julie Walters sketch "two soups" (English comedienne/actresses). To David 537053 - Imagine being in a restaurant and ordering soup for two people - you might say "two soups please".
I agree. I would also say two soup if I was ordering two bowls of the same soup, two soups would be two different kinds of soup so either could be right. There was the same discussion on Duolingo regarding juice. I have a feeling it's a regional thing.
