Do they have some sort of challenge for the King Henry VIII cut? I remember something about 10 years ago, if you finished it, they gave you a second cut.

No challenge. They give you a second English cut slice if you finish your first cut of meat. And you cannot take the seconds to go.

Its not a challenge but you can get seconds or even thirds although they are not full cuts more like small slices

They always offer seconds and thirds fir everything except the City Cut. Your porti gets a little smaller on the second and the third, but they happily give you a to go bag.

Yes, you can get seconds
