This Bath-based chain was London’s first truly French poissonnerie (fishmonger) with a restaurant attached, its entranceway counters piled high with shaved ice, crustaceans and fish. We return regularly, especially for the sublime Dartmouth crab eaten cold and the incomparable zuppa del pescatore (fisherman’s soup; £19), a symphony of delights from the deep. There is also a Marylebone branch.
