Windmill Fish Bar is a family-run fish bar in London that serves fish and chips centered on cod and haddock. The fish comes in a crispy batter with thick, crunchy chips, and you can choose regular, medium, or large sizes. When the fish is fried fresh after ordering, there is a wait of a few minutes, and the shop has seating and a clean dining area inside. Pre-fried fish draws complaints of being greasy with hard batter.
