Mmm, looks good and your last supper should just be whatever you like, whatever you fancy and enjoy. For me, I would probably either go for sushi or maybe some nice burgers/comfort food. Speaking of that, I may have the "last supper" near my CTB time (if I do end up going about CTB'ing), but immediately before it as it may interfere with my resolve or so, but that's just me. Ultimately, only you know how much time you want in between the last supper and the moment in which you decide to attempt CTB.
