I didnt go to the restaurant but it didn't seem to have a dress code as far as the people I seen going in. I'm sure anything you'd wear for a nice dinner date or lunch date is fine.
Respectful puts it best
No... We ask that you dress respectfully for other guests, and trust that works Thanks
I'm not aware of a strict dress code or anything like that, it is for vacation and relaxing. So as for official policy you should be fine.
