Haven't eaten in a Mall food court in a long time, but when I used to work in a mall I had 2 go to's every night I worked, for dinner.
1. Nathans - Double cheeseburger with the BAG of fries and a large Sprite
2. Wendy's - Crispy Chicken meal w/ a large ORANGE HI-C (best drink of all time)
I'd say 2/3 of the time I had Nathans, this time of my life (2004-2006) I was also hopelessly addicted to WoW and was 300+ pounds, fattest I've ever been in my life. After I quit, I dropped 60 pounds and went to live away at college but I'll always have nostalgia for that time in my life between the eating whatever I wanted and playing WoW until 4am every night, simpler times.
