It also used to be ARN, but now it is operated by IBX, thus no complimentary food/drinks any longer. WAW was another one, but it was ceased in 2009 (interestingly enough they're now reinstating KRK, but nor WAW).
What you mean is, WAW ceased to exist as a route in the timetable, not that free catering ceased to exist on the WAW route, if I understand correctly. So free catering still exists on IST and ATH, right? What about MOW?
I noticed that Iberia Express have also stopped serving the German cities and it's back to mainline now. I wonder what all that was about.
Looking at the economy BOB menu in the link in post #16 above, the choice seems to be not so bad. Ok for a shortish flight, maybe.
