AC food offering has usually been:

Breakfast: Oatmeal, Juice
Lunch: Soup, Chili, Chips & Salsa, Potato Salad, Hummus, Regular Salad with one dressing option

I'd eat before going if that's your lounge choice. Food is OK for snacking but not worth going out of the way for lunch. Other issue is that they're often slow to replace food so it may be more limited than what's above.

Haven't been to the other lounge so can't offer a comparison
