This is a work in progress. Attempting to map the availability of Cadbury's Twirls in Central London, with notes on the storage conditions and pricing.
You appear to have missed the off licence about five doors down from Maryland Supermarket, whose awning says, interestingly, The Grape Wine.
I think by that stage, I was getting a bit tired. It had been a long day of Twirl hunting.
I expect you had a carb crash from all that sugar.
