Rescue remedy...

An all-night flight - a 14-hour night - left us at Heathrow feeling distinctly wabbit (if this word is new to you you're probably not Scots, but it's very guessable). And then we found Carluccio's, just by the check-in desks in Terminal 5. At this early hour, it was almost empty, and service came swiftly. I ordered tap water (wonderful to know it was safe!) and an espresso, and told the lovely Italian waitress to come back later.

Two glasses of water later, I ordered green tea and a collection of toasts and croissants with butter and clementine marmalade.

At the time, it seemed the best meal I'd ever eaten ...
