Las Mkt will do the trick if you need something to satisfy your hunger before a flight. My husband and I stopped here before our flight for a quick bite.
The menu is pretty simple for lunch and dinner. There are several varieties of flatbreads, sandwiches, and salads. For breakfast they also have a few sandwich options. The location is mixed in with a couple of other food spots in a food court style setting. There are tables in the area for all of the restaurants. We didn't have a problem snagging a table.
We both ordered flatbreads. They weren't anything to write home about, but they were good enough. The crust was crispy and the amount of topping was about right. It did take about five minutes to get our flatbreads. It isn't Burger King so don't expect it to be ready by the time you pay. Pricing for the flatbreads wasn't more or less than typical airport food.
