"Can I get two of the same bowls?"
I'm not sure of the context - Am I looking for bowls to purchase, and I see one bowl I like, but I need 3, so I ask for 2 more bowls with the same pattern? Am I in a restaurant, and someone ordered a bowl of soup, and I tell the waiter - I'll have two more bowls of the same - ??
I wouldn't say can I get two of the same bowls. Is this a British saying?
This is Japanese course, therefore I assume Japanese sentence is made first. 'ちゃわん' is a tableware that is used to put rice. It is common for Japan. This sentence is used when to purchase. For example you find favorite one in a shop, and you say about the number that you need. In the case, this English sentence is not suit?
