Im a frequent user of the Exec Club Lounges in BDA. They are actually BA lounges, as opposed to those operated by a 3rd Party. That being said, don't get your hopes up. There is no pre-flight dining in either lounge. The F lounge is very small, 12-14 seats from memory, and at times is limited to First passengers only. (I have been refused entry with a gold card once, due to capacity constraints.) The F cabin is full on a regular basis on the overnight LGW-bound leg, (esp. on Thursday & Fridays) The staff are friendly & professional, but the lounges are pretty basic. That being said, the hooch is free, (an important point on an island where a loaf of bread costs $6)
