Well, the ones in the Bronx (like Piper's Kilt) don't seem to have websites. But Piper's does a have a Facebook page.

The bigger joints in Manhattan seem to have their own sites. St. Andrews (on the west side) is one of the better known places. I went to a Christmas party there a few years ago, and I've gone back several times for dinner. Good steaks and whatnot. They also own a half dozen other places in the city. The links are at the bottom of the St. Andrews webpage.
