I found an incredible coffee-to-go shop in London which deserves being recommended. There is a choice between coffee from the espresso machine and filter coffee. If you choose the latter - which I did - they grind coffee beans especially for you, pour the powder in a filter and brew the coffee as you wait. You see it drip directly into the paper cup. Not very economical, I admit, but obviously successful. Each time I go there to pick up my hourly dose, I have to stand in line. I don't mind though, the shop is filled with smells of warm pastry the likes you can only find in Vienna. Next time you're in London, go to Monmouth Street in the West End and spoil yourself.
