Hi,

Welcome to flyertalk frankfab and the BA forum

The meals will be lunch ( served after takeoff) . It looks like a 1315 departure for flights just now so assuming an ontime departure ( then allow 30mins for taxiing), there will be a drinks and nuts service first so probably expect the starters to come round about 1500 ( say 1 hr & 15mins after take off).Might be a few minutes later depending on where you are sitting in club world
Breakfast in CW is likely to start roughly about 2 hrs or so from landing
Others may provide more exact timings.

I would probably have a light bite to eat in the lounge prior to boarding ( and possibly carry some food with you for mid flight snacks as the club kitchen content reports have been mixed here

Regards

TBS
