There are some pretty good options. Three main areas. At Cornerstone up by the bus loop, Uncle Fatih's has a franchise, there's a totally decent burrito place, a poke place, a sorta upscale pub, a Vietnamese place that does solid and cheap pho and banh mi, there's a Taiwanese noodle place that I haven't tried but is always full.
There's the food court in the MBC down a level. Mexican food, decent. Indian food, okay. Chinese food, decent but on the expensive side. Bubble waffle place also sells stir-fry and rice and stuff. And a bubble tea spot.
Third area is the east AQ cafeteria. It's aight. There's a subway franchise.
