Monmouth Coffee Company

The original Monmouth Street shop — the one the whole company took its name from — tucked into a narrow Covent Garden alley since 1978, long before 'specialty coffee' was a phrase anyone used. The street itself sits in Seven Dials, a small warren of seven converging roads at the edge of Covent Garden that's kept more of its old London character than the tourist-heavy piazza a few minutes' walk away, and Monmouth has been part of that character for nearly five decades. Still run with the market-trader directness that history implies: no oat-milk menu theatrics, no latte art competitions, just good beans sold straight.

Monmouth roasts its own coffee at a site in Bermondsey and sells it whole or ground at the counter, alongside a strict bring-your-own-cup policy instead of paper — an environmental stance the shop has held long before it became fashionable elsewhere. Closed Sundays is a rule the shop has never bothered to soften for tourists. Yelp's listing marks it as dog-friendly, one of the more specific, sourced data points found for any shop in this guide.
