Tucked below the City’s Merchant House, a small, characterful bar named for the two-masted sailing ship – and, perhaps, for a ship’s own lock-up
The Brig @ Merchant House carries a 4.4 across 47 reviews, and it earns a close look from the Prat’s desk. Its name is a piece of pure nautical shorthand – a brig being a fast, two-masted sailing ship, and, in older naval slang, a ship’s own prison.
City of London, near Bow Lane (north bank)
The Brig sits below Merchant House in the heart of the City near Bow Lane and Cheapside, on the north bank – a geographic stray in this south-bank survey, caught by the scrape’s reach. We flag the bank plainly; it is one of the City’s best-hidden little bars.
What a brig was
The naming desk unpacks the word. A brig is a two-masted sailing vessel, square-rigged on both masts – fast, handy and hugely popular in the age of sail for both trade and war, crewed by merchants, privateers and navies alike. The word is a shortening of “brigantine,” and it carries the whole romance of the tall-ship era in a single crisp syllable. For a bar heavy on rum – the sailor’s spirit above all others – it is a name that conjures the deck, the rigging and the long voyage perfectly.
The ship’s lock-up
There is a second, saltier meaning the desk cannot resist. In naval usage “the brig” came to mean the ship’s own prison or cell, where drunk or disorderly sailors were confined – a sense that survives in American military slang to this day. A hidden, below-stairs bar cheerfully naming itself after a ship’s lock-up is making a wink of a joke: come willingly to the brig, this time, and enjoy the confinement. It is exactly the sort of knowing, characterful name a good City speakeasy trades on.
A ship in the City
The Brig is the hidden lower bar of Merchant House, a characterful City drinking den secreted away near Bow Lane and Cheapside, in the tangle of ancient alleys at the heart of the Square Mile. It specialises, fittingly for its nautical name, in rum and gin, and trades on exactly the atmosphere its name promises – a snug, below-decks feel, all the more appealing for being tucked out of sight down a City lane. The naming desk approves of a bar that carries the romance of the age of sail into a landlocked City courtyard.
The tiniest sample in the survey
The Brig holds a 4.4 across just 47 reviews – by a wide margin the smallest sample in this entire survey. The Prat’s economics desk reads such a figure with care: a rating built on so few reviews is far more volatile than one drawn from thousands, and can swing sharply on a handful of verdicts. What it points to is not a mass verdict but a hidden gem, known to relatively few, and warmly regarded by most of those who find it.
Verdict
A 4.4 across just 47 reviews marks the Brig as a hidden City curiosity, warmly liked by the few who seek it out. A concealed rum bar named for a sailing ship – and slyly for a ship’s lock-up – is the naming desk’s kind of characterful wink, and a fitting note on which to close the Bermondsey survey. The Prat descends willingly into the Brig, orders a rum, and calls the survey complete.
