Kick off a day of sightseeing with a hearty breakfast at Otto & Frank, located right along buzzy Tkalčićeva Street in the historic heart of Zagreb. Be sure to grab an outside seat and then choose from dishes like oatmeal with apples, cinnamon, vanilla bean, and honey, and sunny-side-up eggs with grilled bacon, tomatoes, and toast. Also on offer is a traditional Zagreb breakfast of poached eggs and grilled ham with cottage cheese, sour cream, radicchio, radishes, and spring onions, which is best when paired with a cup of kava s mlijekom (coffee with milk) and a little people-watching.
