Chelsea Market is crowded and can be tourist filled. But when a local finds something as delish as Fat Witch brownies there, they will battle the crowds. The brownies are great to give as gifts too because they aren't overpriced, are packaged well and ship very quickly!
It is more low key than going to other well-known cupcake or bakery spots. These brownies are very easy to travel with and everyone I know whose had them New Yorker or elsewhere has loved them.
Brave the crowds - it's worth it.
