Fish and chips is a great British tradition - and this place does it both well and cheaply. Cod, chips, and a cup of tea will set you back just under a fiver here, and less (about £3) if you have it wrapped up in paper (lots of salt and vinegar) to take-away.
This is in many ways a typical fish and chip shop - the cooking area goes on down once side of it, behind a counter, and there are 5 tables with benches the other side. When you go in, go to the counter to order for take away, and sit down for service if eating in. On the menu are things like cod, haddock, skate, various pies (cheese and onion, beef, etc), sausages and rolls, all with chips. There are also the traditional side dishes of picked gherkins and onions, bread and butter, and tea, and well as soft drinks and coffee.
This is a good, friendly, busy place to try a traditional British meal.
