Answering my own question from a few weeks ago since flew this yesterday.
Lunch 90 minutes after take off and afternoon tea about 90 mintes before landing on LHR-NAS but just a packet of nuts and drinks on the 1 hour trip NAS-PLS, which I think is rather disappointing to say the least when I can get a meal and drinks service on the 35 minute flight LHR-MAN!!!
Food wise, had soup which was ok, the fish was excellent but had a few bones and cheese was boring and BA could do better with cheese.
Afternoon Tea was good apart from the scones being luke warm.
Soup
The fish main course
Afternoon tea- scones were luke warm but other than that was good
