Sailed on Sky ex Southampton to Norway earlier this year.
Had Roast beef three times in the buffet....very tasty and juicy, but only once was it presented as medium rare (in parts) the other times it was medium (but juicy)
I am not sure whether it was the server's training, their knives not very sharp, or the angle they carved at....but having requested 4 times (yup had seconds on one occasion 🙂 ) for "thin slices", they were unable to deliver. On the first occasion I did ask the server to try again.." please can I have it a little thinner" and it was carved thicker than the first....heyho.. What I love about these large joints in the buffet is you can see the meat, have as little or as much as you want, and also ask for it to be carved from an area on the joint that suits your tastes. Preferred it to the MDR offering.
