In 1976, the New York Times published an article entitled "You Can't Judge a Bagel By the Decor Around It" about the new chain of bagel shops called Bagel Nosh. This Manhattan chain was apparently very successful - it spread as far away as California, and several copycat franchises popped up. It does not appear that the current California and Arizona company by the same name is related - according to their website they started in 1993.
In general the article is about Bagel Nosh, and not unlike some of the glowing descriptive articles written about Dubrow's at different times, but what I find very interesting is that the owner of Bagel Nosh compares his restaurant to Dubrow's:
"'If you look in here and compare our crowd to the people you see next door at Dubrow's,' (Thomas) Quinn said by way of explaining his Seventh Avenue and 38th Street location, 'you'll notice we get the women and girls while they get the rackpushers and more traditional garment district types.' Women, in fact, outnumber men at lunch in that location by about six to one and, in general, exhibit a sort of career girl fashion awareness in dress." (New York Times, August 31, 1976)
