Sunday brunch near Fort Lee?
The Farmhouse in Cresskill is in a beautiful modern-chalet lots of wood building, however it is quite casual. The tables are mostly laquered wood picnic-community tables.
The food, however, is outstanding, unique, and creative-- freshest ingredients.
If, however, you are looking for a gorge-oneself unlimited buffet with standard stuff, I heard that Amalfi in Cliffside does a giant one on weekends.
