Usually, Southwest Airlines' gates have boring food, especially if you have an early morning flight. I was delighted to see that good ol' La Grande Orange has a huge restaurant/shop here. It's not a sit down restaurant so you can just purchase your stuff, wait to be called, and then find a random table.
It was early, so I only ordered a pastry and chocolate gelato. The morning bun $3.30 was warmed upon my request and it was sugary and good. The flavor of the chocolate gelato $3.50 was good, but there were too many ice chucks. They seem to have a good variety of breakfast, lunch, and dinner options.
