When I have been on sleeper between Albany and Boston, we were always served a meal from the 448 and 449 menus by our sleeper attendant. There are only two choices, but they are NOT regular cafe fare and the food is significantly better. I understand that's not the case right now, though (if you get anything, even if you are riding in the split Business Class car, from the sound of it the food will probably be regular cafe fare).Others can confirm, but I believe that the displaced sleepers in the BC split were given some type of box lunch from the cafe. They wouldn't have gotten much more at any point since the diner comes up from NY anyway even when the trains join.
