I was there for lunch and wore a nice blouse and slacks.
Nice jeans and a collared shirt would be fine. I'm not much for blue jeans myself. For women, I think a nice top and slacks, or a dress is okay. The main dinning area is rustic. I know you'll enjoy the atmosphere.
As a male, I'd wear slacks or nice jeans and a collared shirt, maybe a tye depending on the time of year. It's a cool place to dress up for
