we had a lovely breakfast "out" ... with average coffee, which was disappointing, as i had seen that they had a beautiful 3gp LM on the bench...One of the worst cups came from a newish La Marzocco machine! It was like someone having a Ferrari and crunching gears. Rather than look for the type of machine used, I learnt to look for things that the professionals were doing wrong.
the totally overworked barista (making coffee and managing the waitstaff at the same time...) dosed, knocked, dosed, levelled with the lid of the grinder, tamped "somewhat", then knocked the tamper against the side of the PF so the grinds flew everywhere, then tamped again lightly and polished... when she then turned the PF over to get rid of the loose grinds, the whole puck fell out, and she had to start again ::).
because i had asked for a small double shot latte (and it had good microfoam) the coffee tasted reasonable, although still slightly over-extracted...
still, the location was brilliant, the food was good, and it was lovely to be out and about. :)
