I'm jumping in my seat at the thought of Krispy Kreme. The Holborn branch opens at 7am, and there's an early morning discount too.
Pre-emptive sugar rush - even stroopwafel bits can't compare!
(Then again it might be that listening to "Denn Alles Fleisch, Es Ist Wie Gras" is also getting me jittery)
[Addendum: Jolene just reminded me of fresh cornish cream tea as well. OMG.]
