Delmonico's

"Yes, this is one of the city’s oldest restaurants and it may have been the first restaurant in town to serve a hamburger in the 1870s. But more important, the hamburger, made from wagyu — available at lunch in the dining room and all the time in the barroom — is splendid, with the bacon and a sort of cheese fondue poured over the top. The fries are also excellent." - Robert Sietsema, Eater Staff
