Arrrggghhh and Yuk to boot! I was sprinting from meeting to meeting on the Horseferry road yesterday and was desparate for a coffee. Eschewing Starbucks I did what I promised never to do again and went into Pret for a double espresso - YUK and Blegghh it was like sucking on charcoal briquette. In fact it was so bad I took it back and got my money back which they happily gave me!!! It can't have been isolated as on the way out I bumped into an old friend who was just abandoning a cap which he said also tasted burned.
Later... went into a coffee shop at the other (river) end of Horseferry Road and ordered a double espresso - watched in horror as they picked up a PF from the counter, examined it, saw that it was still full of grounds and after trying to knock them out resorted to trying to dig what was clearly a very cold and *very* solid cake out of the PF with a fork. I didn't hang around to find out if they were successful.
Much later... went to Casellas just of Salisbury Sq (just off Fleet street) v good espresso - slightly fruity at the start with general smoothness a slight bitter lingering after taste and just the right amount of body. It was so good that I stuck around and had another just for the taste of it.
Didn't watch the technique but would happily recommend it to anyone around Fleet Street in need of a coffee in working hours.
