There's an angelic new coffee bar in N1. Saintly, one might even say. I read about Saint Espresso, which opened a few weeks ago on Pentonville Road near Angel Tube, in Caffeine Magazine when I was at The Gentlemen Baristas last week and promptly forgot its name but not its address. Luckily, it is only a ten-minute walk up the hill from my office, so I figured that even if I had imagined the whole thing, I wasn't going too far out of my way. More luckily still, Saint Espresso was indeed there…
