I have eaten many a mediocrity when it comes to LA donuts. There was a time when I thought that Stan's in Westwood Village was a first-rate donut outlet, but I was wrong. The best I have had are the divine creations sold by the fine people at Primo's on Sawtelle just north of National. Mrs. Primo runs the place with her kind and friendly husband, and they make excellent butterflies, orange frosted cake donuts, glazed raised donuts and melting buttermilk bars. Butterflies are kin to donuts, but their form is more complex. (The bagels sold in the nearby mini-mall on the southwest corner of National and Sepulveda are also fine.) Please let me know where else in southern California light donuts are made in small batches over the course of the morning so that they are always fresh. And make the trip to Primo's--you will not regret it.
NB: I am not interested in Krispy Kremes.
