Long been a fan of them, though it's been a long time since I had one (or, found one worth having).
They had Brennan & Carr on a recent Diner's, Drive-ins, and Dives and, poking around a bit, I was happy to find there's a Rockville Center location,
However, despite the promise of the website, the location is long since closed.
Anyone know where to find one--a place that roasts the beef on the premises and makes the dipping juice? I live in south/east Nassau but don't mind a reasonable drive (I can't easily explain why, but I have a mental block about driving to Brooklyn/Queens).
