British Airways lounge Terminal 4 Heathrow
TW6 3XA 

Whilst waiting for my flight from London to Singapore, I spent some time in the BA lounge in T4 (since moved to T3, I think). It wasn’t quite as comfortable as some of the new lounges in T5, but still not bad and the food is the same in both. See the photos below of the salad bar, pastries and (the usual) bacon rolls.
