Best LHR T3 OW lounge for breakfast

Not strictly a BA question, but you folks are the most likely to have a good answer:

I’ll be flying from LHR T3 in a few weeks, and due to a quirk in timings I’ll be arriving at LHR at 8:30am, around 5 hours before my flight. I’ve recently hit BA Gold/OW Emerald, so I’ll have a bunch of new lounges to choose from. I’ve previously only ever taken afternoon/evening flights where I’ve prioritised alcohol/dinner offerings, so the breakfast selection is a bit of a blind spot for me.

From what I’ve read the Cathay First lounge is generally the best lounge, but my colleague tells me their breakfast offering is a bit disappointing, and that the AA/BA First lounges will have a better breakfast selection (which surprised me).

I’ll have my partner in tow who probably isn’t interested in lounge-hopping, so interested in your thoughts. Is the Cathay First lounge still the best in the morning, or do you recommend another?
