Delta employee food court is closer than the sims- an easy walk. Im not sure about hours but they have pizza, salad bar, chick-fil-a, starbucks, sandwich bar, even a drug store. Dont forget to bring your ID. The security guard will direct you to the right door. Great people watching too. These are the people running your airline.
Hotel rooms have fridge in every room, and a microwave next to the ice machine on every floor. Amazon Now will deliver groceries if your gonna be there for a while.
