Getting in a bit late on the thread - I've eaten at Peter Lugers a few times, I can't remember if it was in LI or in Brooklyn, it's been over 15 years.
Good to know it's still around, I remember it was a big deal to go there. A top place to get steak.
Went and looked it up on the web, found the Wiki.
