What is open on Christmas day?

[jaykat]

We will be arriving in Washington on the afternoon of 25th December. We will be staying at the Embassy Suites, Convention Centre. I am trying to find somewhere nearby where we can have a casual dinner - we dont need a "christmas" dinner as we dont celebrate Xmas, just a simple, quick, not too expensive meal (for 2 adults, 2 kids).

I looked into Matchbox which is near our hotel and has a great looking menu, but they will be closed that day. Any ideas??
