From Royal's Website:
"What's Included
Unlimited visits to speciality dining restaurants every night of your sailing and lunch on sea days.
For restaurants with a la carte pricing, you’ll receive a $35 food credit, with the exception of Port Side BBQ and Playmakers which will be $20.
For ships with these venues, Teppanyaki/Izumi Hibachi is included, with a $10 surcharge, Chef's Table is included, with a $49.99 surcharge, and Dadong is included, with a $35 surcharge. These will be charged once onboard."
So it'd be, basically, $100 for two people for the Chef's Table. And the wine is included (probably where that $50 charge is mostly coming from).
