You can find Joplins on the left hand side as you leave Wilderness heading towards Knsyna. It is well worth a stop if you could do with a steak, egg and chips. But its only steak egg and chips. There is a limited menu. Limited to steak and chips with a choice of a fried egg and garlic butter.
I stop regularly. You can also get Rock Shandies or something thats cold which will quench the thirst while you wait for them to prepare your steak
