As the name suggests, bunshop will major on the duo’s famed buns (the beef and barley variant is one of the Marksman’s most popular menu items).
Filling options on bunshop’s opening menu will include welsh rarebit and mushroom as well as the classic beef and barley with horseradish cream.
Buns will be served with a side of devilled fried potatoes, seasoned with English seaweed instead of salt.
The drinks offer will include ‘proper builders tea’ and seasonal sodas.
Filled, baked and then steamed, the savoury buns are priced at £4 each.
The pair has collaborated with design studio A Practice for Everyday Life to create stylish packaging for the new brand.
