BA Arrivals Lounge LHR
With an on time arrival and prompt baggage delivery, we had plenty of time before our driver picked us up at 11AM.
Mrs. SFO decided she'd rather sit and wait than walk to and explore another lounge, so I walked off to sample the Arrivals Lounge.
The pleasant lounge dragon asked for my BP and then wrote out a pass to the Concorde Breakfast Room, reserved to F pax. Functional space with multiple seating areas and eager to please wait staff, comically pushing food like my grandmother.
I was just planning on having a yogurt (cherry)...
But friendly CBR attendant insisted I have more. "Try the Eggs Benedict. They are wonderful" OK, if you insist. Meh, not so wonderful. Tasted about as good as it looked, lathered in hollandaise sauce. 
Next: Gatwick BA First Lounge and the Priority Lounge.
