Fish and chips or fish 'n' chips (also in Scotland, northern England and Northern Ireland: a fish supper), a popular take-away food, consists of deep-fried fish in batter or breadcrumbs with deep-fried potatoes. For decades fish and chips dominated the take-away food sector in the United Kingdom, Australia, and New Zealand. They also have considerable popularity in Canada, Ireland and South Africa. Denmark and some coastal towns in Norway form another fish-and-chips stronghold, referring to the dish as fiskefiletter ("fish filets").
In the United States, fish and chips (usually the thinner sort of chips, known locally as "fries"; see below) have spread across the country as mainstays of chain restaurants such as Long John Silver's, Captain D's, and Arthur Treacher's Fish and Chips. The southeastern states mostly use catfish instead of the whitefish traditional elsewhere.
