It's under 500 calories if you go with a small size, but I got a regular size; it's comparable to a Subway Footlong in size and is enough for two people. The price on a regular was $6.39, but I received mine for free courtesy of Quiznos.
The focus of Quiznos menu revamp seems to be a general upscaling of the menu along with the offering of new flavors or forms not offered by competitors. The distinguishing feature, or rather features, on the Chicken Milano are the sun-dried tomato and basil pestos. The sun-dried tomato pesto lines the bottom half of the bread while the basil pesto takes the top. Both deliver strong, but not overpowering flavors that aren't often present in most subs. Between the two, it was a little salty though.
The veggies were fresh and the seasonal lettuce blend appeared to be mostly romaine with nary an iceberg in sight (I think the blend includes iceberg lettuce; I just didn't get any).
Overall, a very nice sub. I especially liked the chicken and the pestos. If this is the new direction of Quiznos, I approve!
