Bream

We are headed to Bermuda on Norwegian Gem next month. We've never been to a Brazilian Steakhouse and thought we would use our included dinner vouchers on Moderno. We like meat, that's why we wanted to try Moderno. However, we don't like very fatty meat and especially don't want undercooked meat. Is there any way a diner can specify how they want their meat cooked? Or will we have to channel our inner caveman?
