Chip shop is short for fish and chip shop, also known as " the chippy " or " the chipper " ( the latter esp used in Ireland ). So really its specality is fish and chips - proper Brit chips are usually thicker than french fries ( although I have seen pictures here on Roadfood of some fries that would not look out of place at all in a decent Brit chippy ! ) and usually cut fresh from real potatoes, altho some places like cheap caffs and pubs will use frozen made from re-constituted spuds
Its just easier to say chip shop, lol. They dont just sell fish and chips, they also usually sell things like all kinds of pies, sausages, saveloys, all manner of things in batter and sides like pickled onions, wallys ( gherkins ie huge pickles similar to dill pickles but not as good ) various battered veggies, curry sauce, gravy and of course peas
inc the famous " mushy ".
