I can tell you that pre-COVID on most of my monthly EWR - APAC routes I received really good service -- even my picky Japanese wife (why don't we take NH) likes it -- however -- on the EU flights it was honestly more hit and (mostly) miss... I don't really eat on UA flights any more but tomorrow I'm on LHR-EWR - after a really nice GF BAH-LHR flight where I WILL eat and drink actual wine -- I might order the UA food just to report on it -- I'll try to skip breakfast in the LHR UC but they do make a mean sausage so no promises....
