Flew that route in Business Class last week. The Menus changed on the 1st of Aug. so maybe they're just slow updating the website they normally have the details there.
DUB-BOS was Bacon & Cabbage or Irish Stew or Fish Pie. I can't eat Bacon & don't like Irish Stew (I'm Irish) so had the Fish Pie & had to send it back. Completely dried out.
BOS-DUB was more what I was expecting: Beef, Chicken or Seafood Mac & Cheese. Could have eaten any of the options, had the Seafood Mac & Cheese it was pretty good.
