I could see it being dressier (or at the very least, much preppier) than comparable restaurants here -- I'll likely wear a dress, but men don't need jackets, right? Can my husband wear nice jeans with a dress shirt (and maybe a sports jacket)?
Open Table and Dress Code Finder say Smart Casual; Yelp says Business Casual. I haven't been there, but a sport coat, dress shirt and jeans sounds fine.
A sport coat should be fine. I think my husband wore a cardigan, dark jeans and a collared shirt. (ETA: I looked up the photo on my phone - he was in khakis. But nice jeans should be fine.)
