When is Manhattan the most crowded?

Between 5 and 6 p.m. on the Wednesday after Christmas, apparently:

“You have, on the one hand, all the tourists who are here… Then you have people who have left the matinee and people who are coming to evening shows and eating dinner before or after the shows.” Add the commuters who are still pouring out of offices, along with people returning gifts or using their gift cards.

Agoraphobes: stay away.
