On a sun-soaked corner of Sunset Boulevard, find one of the city’s most compelling reasons to wake up early. Anybody can throw together a breakfast sandwich, but few compare to the one at All Day Baby. A tower of softly scrambled eggs, bacon, sausage and American cheese arrives under a cloak of strawberry jam stacked between a fluffy cathead biscuit. It’s hearty and essential, much like the impressively airy hotcake crowned with ricotta, blueberry compote and pistachio.Not everything is sweet at this charming café. In fact, some things are fried, like the hot fish sandwich inspired by Nashville’s hot chicken. Neat rows of cookies, pies and breads in the pastry case are yet another temptation from a restaurant that all but induces a nap.
