Generally you will have to buy whole fish or sides of fish. They will portion fish up for you though.
It’s a great experience and you can also get a bacon & scallop roll from the tea shop in the corner for like £3.50
Billingsgate is about buying in bulk, went down with some friends years back and it’s good to do it with a couple of people so you can buy and then divide later depending on what everyone’s tastes are.
Does anyone have any experiences buying fish from Billingsgate market as a consumer i.e asking for a couple of pieces of cod?
Or am I better off just going to one of the nearby fishmongers around Roman Road
