I went with Au Bon Pain. Gallagher's looked great but the sandwiches run $12-$ 18, which is more money (and likely food) than I wanted.
I haven't eaten McDonald's food in over 10 years, though I did get a cup of coffee at one a few weeks ago.
Good thing I took food with me-the CO flight had cheesburgers. While I was surprised they served a hot meal, the burgers looked pretty rough.
