Try a Belfast Bap (scrambled egg, irish bacon, three sausage links and cheese in a roll), a delicously beef-and-oniony sausage roll or one of the amazingly light raisin scones.
Not a fan of soda bread, or any baked goods that taste like I just ate a box of Arm & Hammer. Their shepherd's pie is ok, but far from authentic-- you need the original lamb stuff in there.
