High Quality Content by WIKIPEDIA articles! A beefsteak is a type of banquet in which sliced beef tenderloin is served to diners as all-you-can-eat finger food. The dining style originated in 19th-century New York City as a type of working-class celebration but went into a decline in the mid-20th century. Resurrected by caterers in New Jersey, the beefsteak banquet style is now popular in Bergen and Passaic counties in New Jersey, and is enjoying a revival in New York City, where the style originated, due to the reemergence of a biannual beefsteak in Brooklyn.
