I've seen Currito restaurants in a couple airports and finally decided to try this location at PIT a couple days ago. I ended up getting about what I expected to get, though: an overpriced burrito that didn't taste quite right.
I tried the Thai curry burrito with chicken, and while the ingredients all seemed correct and Thai or Thai-inspired, something about the combination of the tortilla and the peanut sauce destroyed the whole meal for me. It also didn't help that my burrito was two-thirds rice and the remainder contained very little chicken.
Another reviewer here mentioned trying the "classic" burrito instead of any of the fancy or ethnic-related burritos, and based on my experience, that's probably very good advice.
