Translation:Waiter! Please give us two bowls of rice.
"Waiter! Please give us both two bowls of rice"- is this wrong??? If it's I need to learn English as well
I would say that English sentence might be confusing, do you each want two bowls, or two to share.
Also note that the Chinese sentence doesn't specify how many people there are in 我們, it might be a family of five wanting two bowls of rice to share.
