Murphy's Irish Bar (down the non-Schengen D gates, just to the right when the corridor forks) does a very decent Irish brekkie for 11.95, if that's your thing.

Otherwise, I'd head to the Brasserie on the top level of the D departure lounge. The others are more or less pass-through-and-put-on-your-tray-pay-at-a-central-area-and-sit-in-the-general-feeding-area places.
