Smažák is short for smažený sýr: a thick slice of cheese coated in breadcrumbs and fried until crisp and golden outside, with melted cheese inside. It is a much-loved Czech and Slovak comfort food, usually served with potatoes or fries and tartar sauce. You may also find it in a bread roll as a quick street-food favourite. It is normally vegetarian, although ingredients and frying oil can vary by restaurant.
