No dress code.
Nothing official that they will turn you away for. But it is one of the nicer restaurants. If you don't want to feel out of place, dress up a little.
There is a dress code, but loosely followed. We've seen people there in very casual clothes. We've generally gone in jeans and a casual but nice shirt.
We went in late at night after a long day with my nieces and we sat at the bar and we weren't dressed up, had dinner at the bar and no one said anything to my fiancee or myself about being under dressed.
Yes, collar shirt for men, dress for women
