be good for a free lunch

[PeaceMaker]

Justin Powell, the Funcoast.com editor (who's always good for a free lunch), and I started our meal with the Fondue au fromage, a bubbling crock of gruyere and parmesan cheeses served with house-made focaccia and seasonal fruit.

Please what does it mean when someone is good for a free lunch/dinner?

thanks in advance

Best Regards

Meaning Mr. Powell usually invites his visitors to a lunch, for which he pays.
