I got lunch from CFA yesterday - original chicken sandwich and 4 nuggets. Fine, I guess but underwhelming and not something that I'll ever crave. For me, CFA is a Hall of Fame breakfast place with their spicy chicken biscuit w/cheese, but I'm never excited about going there after 10:30am.
What does excite me? Flying through O'Hare and having the chance to get food at Rick Bayless's Tortas Frontera.

So great. I changed planes in O'Hare last week and got an awesome sandwich:
The Pepito: braised beef short rib, artisan jack cheese, pickled jalapeno, cilantro crema, black beans, wild arugula
[I realize this looks like a took a picture with a potato, but I assure you it's delicious.] This sandwich is so good that it actually influences my flight plans - at the margin, I'll choose to connect through O'Hare so I can get one.
I look at the people eating at some other crappy airport place and just pity them.
