Great place for breakfast. Fast, unpretentious service, runs like clockwork. Listen to the shouted orders to and from the kitchen, all in that Italian/New York drawl.
Corner of w78th and Broadway

It is actually Greek! But still fantastic. This is without doubt the best diner in NYC. Although its not on W78th its on W77th & Broadway and they're not Italians they are Greek.
Is this your business?
