Hej K!
Great to hear your trip is getting closer!
I could make it on Saturday 7th to Harrods (worth an experience!)
or early evening of Tuesday 10th, at Harrods again
(7th is preferable for me).
Decaffeinated is available though I'm not sure what "sweet and low" mean - probably available under a different name: artificial sugar and skimmed milk?
If we are hoping for any chance of meeting up, please let me know by Thursday 29th latest as my worki diary rules my free time at the moment.
Wherabouts in London will you be staying?
Looking forward to hearing further!
Cheers,
Vim
