We used to go to the Blarney Stone near MSG where there was a steam table/sandwich station you could get a corned beef sandwich, mashed potatoes, mac and cheese and like. That has since closed, but I know there must be other restaurants of this ilk in town.
Me and the Mrs. will be in the Times Square area this weekend and need the name of a few places.
I know there's a ton of great, fancy, 5 star type of places in NYC, but that's not us. We're jean wearing, food loving, meat and potatoes folks.
