I've posted about this place in the past,
and Newsday did a bit:
They did a makeover recently, changing from Rebecca's Cafe to the Park Avenue Grill. The changes involved renovations and redecorating, and the addition of an organic menu; dinner service to start in mid-March, and I think they're going for a beer/wine license. Same ownership as before but with an expanded menu.
It still remains pretty much the ONLY breakfast destination for me in the area (S/E Nassau and S/W Suffolk). I've never done lunch there, but the other posters have all been pleased with it.
