Good downtown (or even West Village) lunch place for sit down?

I have a couple family coming in from out of town. They are older, in their late 50s. While we all know "Wilton House" is the go-to, what other places are a good option for lunch during the weekday, not weekend.?

I was thinking Del Frisco's or Halifax. La Isla I like, but thinking it could be too cramped, i'm looking for something more on the scale of Del Frisco's or Halifax. Any other options or is everything mediocre?

Alternatively, could go into the West Village or Meatpacking district. Would like something that impresses them.
