I ended up in the B terminal twice today - around 6am and then again at 5pm. Yes... I had Tortas Frontera twice in the same day. The breakfast sandwiches are a little too much food for me that early in the morning, but delicious nonetheless. Chorizo, eggs, poblano rajas and Chihuahua cheese - could have used a little more kick to the chorizo, but overall fantastic. Cochinita pibil as an early dinner was exactly as BR described above - a little on the greasy side, but delicious.
Over the past month I've been to Tortas Frontera once or twice a week and I can honestly say that it's been a boon. I'm stuck in airports a lot, and they're normally the culinary low point of my week - Tortas Frontera is cranking out food so good that I'd happily
eat it outside the airport.
