The oldest bar in the state of Oklahoma is most famous for the fried chicken.
Eischen's Bar - Home
They are a cash only place and have been that way for many many years. They have great fried chicken. No plates just a piece of wax paper, no silverware. If you ask for a fork it is plastic. The only choice is one whole chicken. Well I guess you can have all the chickens you want but if you want just a breast it will come with the rest of the chicken.
They are always packed.
A buddy of mine works for a large international company. Many managers from other plants came into town for a meeting and they all wanted a taste of the local foods. He hauled them to Eischen's and when he asked for a receipt to turn in for his expense account it was the side of a brown paper bag written with a pencil. He knew the place took only cash so he was prepared for the ticket.
