Spent two hours here last night. Was one of the most pleasurable domestic sky club experiences I've had in ages.
Expansive food offerings, way more than even JFK has. There was a great Pita/Gyro/Rice hot set of food, a full charcuterie board with tons of different kinds of cold cuts and cheese, the normal soups and salad bar but with a bit more option - as well as a special pork chop sandwich on display near the bar. The deserts were great too with an oreo pudding cup and a cheesecake cup along with cookies. They also had packaged foods including salted peanuts and granola bars.
Views were great and the overall space feels fantastic. Such a perfect addition to BNA!
