You ordered the beef on a plane! Expectations had to be low.
Hah, fair! I can't remember what the alternative was, but it was something that managed to sound even worse! (Coincidentally, I ended up getting beef again back from SFO after seeing on the other side of the plane what the alternative chicken noodles were like—they looked (though may not have tasted) like vomit—and that was pretty great, actually.)
What KLM have been serving recently is a mystery. Bowl of grey and it lived up to its billing
I'm not sure I've ever had KLM's long-haul fare, but short-haul the sandwiches just seem to have got worse and worse to the point where both bread and filling are vile. I actually quite liked the sandwiches BA had for a while around Europe: they were pretty small, but they actually taste nice! (I don't think I've flown BA within Europe in over a year, excluding domestic, though, so I don't know if that's still true.)
