Sunday dinner at the Reagon's [Blue Bloods]

I just discovered Blue Bloods. I am on Season 5.

The food looks so real and delicious. It doesn’t look plastic.

I realize that the dinner scene may have a bazillion takes. And the food (if it is real) may not be hot at consumption. But, it looks so good.

Are these dinners catered? Or does the studio have its own kitchen?

Or is it plastic?
