The page linked below, for the Long Island Press, contains some restaurant info. I suspect they're mostly advertisers, but, still, there are a few I don't recognize, which intrigues me. I've lightly edited and shortened the descriptions so they're short enough to constitute "fair use" and not be a copyright violation. Follow the link for full info.
Again, I'm not suggesting this is good or reliable info. Just a possible source of some possibly interesting raw material, tip-wise.
The ones I don't know and which intrigue me (at least slightly) are the following. Anyone know 'em?
