Sauteed mushrooms are also sometimes included, as well as baked beans, and brown soda bread or Fried potato bread sometimes served as an alternative to brown soda bread. 

The Ulster fry is usually served all day. Also, it is sometimes jokingly called : “heart attack on the plate” because of the amount of calories it contains.

You can order Ulster fry in nearly every café in Northern Ireland.
