Look on the website for the times you are sailing *Limited service* just means teas coffee and croissants no full breakfasts I think full service starts at the 7.45 sailing Hot restaurant meals from 11am
If it’s anything like the Hull route I would give it a miss. We used to book the Brasserie on every crossing. We have crossed 3 times this year and all 6 visits the food and service has been shocking. We are booked again next month and shall slum it in the other restaurant to see if it’s any better. We have moved from DFDS North Shields route to P&O due to the ferry size. We feel the DFDS ferry is just too tight for us, we are more relaxed with the car deck on the P&O service.
