200 Degrees Coffee Shop & Barista School, Lincoln

You walk into 200 Degrees and immediately get why people camp here between the cathedral and the High Street. It's the kind of place that takes coffee seriously without being insufferable about it — the baristas actually want to talk you through what's in your cup rather than make you feel daft for asking. The setup works because it's genuinely welcoming; whether you're after a flat white or thinking about doing their barista course, there's zero pretension. The roastery angle means the coffee tastes better than most chains, and locals clearly rate it — the review count speaks volumes.
