British Airways operates both a two Business Class lounges, a First class lounge in T5 and the Concorde Room.
This reports cover the new First Wing at Terminal 5 LHR, which provides First Class and OneWorld Emerald passengers a direct access to a priority security and drops you off at the entrance to the lounge, skipping the madness that the common area can be at Terminal 5.
The lounge food wise has a buffet and a sit down restaurant and a variety of beverages on offer via self serve.
The main buffett area had several fried items and a make your own curry station.
Since I was flying during the afternoon hours, the lounge featured a variety of small sandwiches as well as cotted cream and scones.
A variety of cheeses on offer...
The best feature of this lounge is that they offer Johnnie Walker Blue which can retail at over $200 a bottle. Basically it's heaven for those that enjoy JW Blue and one can even access this lounge when flying in coach if one has OneWorld Emerald status.
some people hate it as due to health and safety reasons, they only serve the burgers "well done". But still it when done well is quite tasty.
