Panopolis

You'll find Panopolis wedged under the Victorian ironwork of Paddington's railway viaduct, where the smell of fresh espresso cuts through the morning commuter chaos. It's the sort of place that takes its coffee seriously without making a fuss about it—the kind where regulars have their order memorised and the staff actually know your name. The pastries are proper, the kind that still have butter fingerprints on the bag, and they've clearly figured out what Londoners want: excellent coffee, no pretence, somewhere you can actually sit down for five minutes before your 8:47 to King's Cross.
