Open on Christmas Day for Lunch or Early Dinner?

Any suggestions for restaurants open on Christmas day? Need a table for 3 sometime between 11:00 and 1:00. Steakhouse, Italian, or perhaps seafood would be great but I'm open to other suggestions. I'm in Oak Park so central Chicago, Rosemont, or perhaps Oak Brook are all doable.

Thanks in Advance!

Thank you Sir(Madame?)!
