Breakfast in Ogunquit?
The Back Yard coffeehouse, tucked away on Rt 1, is a new (as of last summer) little gem, with super coffee and a nicely curated breakfast selection. http://www.backyardogunquit.com/
Also, Breaking New Grounds in Perkins Cove, has solid coffee, a nice selection of breakfast items, and Adirondack chairs overlooking the water. If you get there early you might be able to grab a parking spot!
