I will be passing through LHR Terminal 5 between 7am and 1pm in early July en route to Scotland from the USA.

Where can I get the best espresso at Heathrow, either within the BA Lounges or elsewhere in Terminal 5?

I'm flying BA F and booked a cabana in the Concorde Room lounge for most of my ~6 hour layover. I have some mobility issues, so may or may not be up for a prolonged wander, but I would definitely leave a lounge for a better brew if I'm confident of higher quality, especially where I have plenty of time to wait.

I prefer straight, black espresso. (For other coffee nerds, I also prefer a lighter roast, single origin espresso, with a few Ethiopian and one Ituri from the Democratic Republic of the Congo standing out in recent memory as particular favorites.)

I usually drink one coffee per day and its my greatest vice, so I do seek out the best quality I can find. Searching for single origin espresso in specialty cafés is one of my travel hobbies. It's one of the first things I look for when visiting a new city, right up there with great museums and local food specialties.

I've read about the recent BA coffee collaboration with Union Hand-Roasted Coffee, and I applaud the effort to develop better flavor profiles for in flight bean blends, but I don't see anything about espresso drinks in the lounges. Well, except for many mentions of espresso martinis.

Thank you!
