Kenny Shopsin is famously known for hating publicity and because of his cranky eccentricities, Shopsin remains my culinary hero as opposed to the other Lower East Side of Manhattan magician, Wylie Dufresne. For starters take a look at Shopsin's goddamn menu. His crazed improv-short-order cook cum screaming magic bean buying savant style is one of the last great joys of eating in New York City.
My approach at Shopsin's is the exact opposite of "the customer is always right." Until I know the people, until they show me that they are worth cultivating as customers, I'm not even sure I want their patronage.
If you subscribe to Tasting Table or read Counter Culture obsessively, you will love Matt Mahurin's documentary I Like Killing Flies which really dives into the soup to nuts and bolts story of Kenny.
The old Shopsin's location in Greenwich Village was legendary but Kenny is still working the magic at the new location in Essex Street Market. So go see him but beware: He bites. Or just buy the book already.
