I know that they're still serving food after Illuminations. I think (not sure though), that they're open til at least 10:00. Just be aware that many people have the same idea as you-going to B & C after Illuminations and so it's PACKED! I thought I was one of the few with that idea one night, and the CM there told me "They RUN over here after Illuminations, I think." When I got there (9:30 or so) the wait was over 1/2 hour. Late afternoon there was no wait.
