About us

A passion for excellence

Based in Cockfosters North London, Poisson Quality Fishmongers is a traditional family run business which was established in 1959, and is now in the capable hands of the third generation, Ross Arnold.

With a passion for excellence we provide our customers with fish that is top quality, exceptionally fresh, healthy and nutritious.


A dedicated and experienced team

At Poisson we focus on fulfilling the needs of our customers, many of whom travel across Hertfordshire and London in pursuit of our excellent fish.

We have a dedicated, experienced and friendly team to help you choose your products, and to offer advice on recipes, preparation and cooking.

“Day-boat fish” or fish brought in by small boats

We are renowned for our dressed salmon and fish fried in matzo meal, and have a large prepared-food section with a choice of gourmet meals and delicacies made on the premises. We also have a large range of salads and sauces for you to choose from.
