I called them before I visited and went with smart shoes, chinos, shirt and tie and a jacket. At that point I was under dressed compared to a lot of men but just went with what I had while visiting NY.
From website: Jackets are required for gentlemen for dinner and anytime after 4 PM. Ties are preferred. Weekend Lunch and Brunch can be slightly casual, but too casual is never allowed. Appropriate footwear is required at all times.
Jacket slacks shoes neat

For men coat is a must. I would recommend nothing less of a suit or tux. For the ladies something fancy .
