I stopped by here with a coworker before our flight. This might be my new airport spot, hidden towards the end of one of the terminals. This place has by far the healthiest meal selection, at a fairly reasonable price. The portion sizes aren't huge, but the food taste fresh.
For lunch I ordered the Marconi almonds and beat and avocado salad. The almonds were covered in brown sugar that wasn't overpowering and had a nice sweet flavor. The salad itself was rather small, but tasted excellent with a delicious vinaigrette dressing. I also tried some of my coworkers truffle popcorn which had a nice helping of parmesan cheese and oil on it. I thoroughly enjoyed it!
I really like this place because it has healthy options and the flavors are there. The only reason this wasn't a 4 star for me is because the portion sizes will leave you a little hungry afterwards. However, given the options at the Pittsburgh airport this is one of the better ones out there! Definitely go here if you're looking for a healthier meal (or wine).
