Gotta disagree with Dan the Man on this one - of all the grab & go options in CLT, Wolfgang Puck places first. It's important to denote the price gouging is assumed, as it's an airport and every pre-packaged sandwich or salad rides above the $10 mark. Wolfgang Puck is no different.
Where the wheat separates from the chaff is in actual execution. I got a fresh, crisp Chinois Chicken Salad for $11 and I ate the whole durned thing. A napa cabbage and romaine base with a mustard-soy vinaigrette, crunchy wontons and real herb roasted chicken. It was more than airport good, it was actually good.
Avoid the sandwiches, and stick with the greens. You can see everything inside.
