I'm guessing there are less and less of these still extant, simply due to economics.
So last night, late, 2 friends and I were walking eastbound on 14th Street from 9th Avenue, when one suggested we stop at The Donut Pub. I thought I didn't hear him correctly, and that he was referring to a bar.
I never knew this existed. I don't get uptown much. The donuts are excellent.
