Good, casual eating in loop

Is there such a thing? I rarely seek out food in the loop, but
I am helping my lady friend run some errands and am starving. Anyone have any suggestions?

"Loop" and "casual eating" can mean a lot of things. After 15 years of working in the Loop I can assure you that there is "such a thing" but it would help if you defined your parameters a little better. Sit-down restaurant? Really good fast food? North Loop? South Loop?
