I really enjoyed my recent visit to the JL/AA (definitely more JL than AA) and although there wasn't a lot of food, the hot and cold items were tasty and they even have a pancake maker like the AS Lounge. Its usually about 20% full when I have visited so never a problem finding a place to sit. I'm not sure why the hot food isn't self service--they actually have an employee taking and filling orders based on the printed menu options--seems unnecessary. With that said, if you have access via AC or AS Lounge+, it's likely light years better than any of the HA lounges with a soda machine and bags of snack mix.
