Don't judge a book by it's cover- this restaurant has very good food! Start with a stack of onion rings and two dipping sauces and order a turkey bacon sandwich on focaccia bread with thick bacon & cheese, lettuce, and herbed mayonaise or the pork bbq melt on an onion kaiser roll with melted cheese and caramelized onion! Kids have their own menu with standard options like mac & cheese or a quesadilla with a fruit cup.

This restaurant is located inside the Lake Murray State Park's Lodge with a slightly rundown facade, but great food! Adults have many different options like a Grilled Pesto Chicken Sandwich on a Kaiser Roll or an Okie favorite like Hawg Wild- a pork shank brushed with bbq sauce and slow roasted served with a side of garlic-mashed potatoes and a veggie. Kids have standard choices, but because the food is priced low, they could order off the adult menu and not break the bank!
