Red Barn's Barnbuster was a quarter pound hamburger loaded with pickles, onions and tomatoes. I think it was meant to emulate Burger King's Whopper. Red Barn also had the Big Barney, which was to emulate McDonald's Big Mac (two beef patties, three bun pieces, thousand-island sauce, onions and pickles. In 1970, the Barnbuster was 55 cents, Big Barney was 60 cents (regular burger was 20 cents). Regarding TV advertising, Red Barn was not advertised so much as McDonald's. Commercials rarely aired on network TV...only local affiliates which had restaurants nearby. I have two commercials: one from 1969, a general promo, and a Barnbuster ad from 1971 featuring puppets (the chicken leg and the puppet that resembled Ernie from "Sesame Street").

Big Barney came out before Big Mac, acording to a Red Barn site I just visited.

That is correct, the Big Barney came out long before McDonalds copied it with their Big Mac. I was part of Red Barn's Management.

Red Barn was the first restaurant of its kind to have a self-serve salad bar, which is very little known. I remember the Big Mac being a copy of the Big Barney. All you had to do was taste one and it reminded you of the Big Barney. My favorite was their fish sandwich though. It was fresh cod and it was delicious.
