We always meant to go to Shula's, and our next trip we want to finally go, but I don't know dressy I need to be. The website says business casual, but if you've been, how did everyone dress? Would I be okay in nice slacks & blouse? Or do I need a skirt or dress? To dress up I'll need to bring an extra pair of shoes. And do men wear polo shirts, or do they need a tie? Thanks for the input.
