Gritty's will be fairly casual but for those of us who will be attending the 20th anniversary at Mt. Ararat you should know that the dress code for that is semi-formal. My advice is don't worry about it. Wear what you want to Gritty's don't worry about appearing too dressed up among the t- shirts and jeans. And so on.
