its the same menu as you would find if your ship had a dedicated haven area, we were recently on the jade, and breakfast was in moderno, lunch at cagney's . no difference between those choices and on any of the ships that have "havens"
aslo since cagney's is one of the "specialty restaurants, ad is moderno, they are not available exclusively for haven guests. for dinners, they are open to all passengers.
by the way, breakfasts menu is amazing!
