I went to Hudson Eatery tonight to show some bitcoin support, but no one there had any clue about paying in bitcoin. I'm not sure how it got on the list here, but they do not accept bitcoin or even knows what it is.

Ya, they were one of the merchants who had accepted Bitcoin at one time (
http://betabeat.com/2011/07/another-midtown-restaurant-hudson-eatery-now-accepts-bitcoin ) however I believe they suffered losses when the MyBitcoin hosted (shared) E-Wallet disappeared and stopped taking Bitcoin after that.
That's one problem with having multiple directories -- there's duplication and sparse traffic, so even if a merchant gets removed from one directly the entry on another may stay until someone reports it and/or contacts the curator of the list.
I no longer see Hudson Eatery on Coinmap so that directory seems to be one to be both fairly comprehensive and current.
