Yes! Its free but fills up very quickly. There is additional parking in the adjacent lot (different entrance) which also fills up albeit a little longer.

Depends on your kids lol

Yes, I saw kids there when I went 2 weeks ago.

No they're not

They have salmon but I think as fillet not steak. Do not remember ever seeing any other type of fish on menu

No.

Unfortunately no Christmas specials at The Keg.

Many locations have a seasonal menu including a pecan crusted steak with goat cheese. I suggest you contact the restaurant directly or subscribe to their newsletter for info like seasonal menus.
