There aren’t a ton of BBQ options at the airport, which makes sense because scarfing down huge helpings of pork, baked beans, and mac and cheese might not be the ideal meal before being squished into a middle seat for five hours. But when Mustard Seed’s tender brisket and slightly vinegary potato salad touches our lips, it puts all thoughts of fighting for an arm rest out of our minds (it belongs to the middle seat. Period). It’s worth the trek to Terminal D to get our hands on a solid Southern meal, and the laid-back vibes of the wood-paneled space feel homey and warm.
