I get to Healdsburg frequently and absolutely have to have my "eggs benedict" fix at Costeaux's. No matter what the variation it is that particular Saturday or Sunday, it will be fabulous. The portions are so huge, though, that I generally split this with my companion. With a side croissant - also to die for - almost, almost as good as Paris! Note though - this option is only available on weekends, but the weekday breakfasts are good also!
