Yes, AK is the hard one for your preferences. Honestly, even though it sounds exotic, QS Satu'li canteen may be an option at AK (unless you want BBQ, then there are several good options in the park), as at Satu'li you can build your own "bowl" and have a choice of Beef, Chicken, Fish, or tofu and then pick; served on salad, or potato hash, or grains with rice. Then topped with whatever sauce you choose (onion chimichurri, black bean, or creamy herb). The decor is nothing like GFC, and neither is the vibe, but the bowls are actually pretty straightforward.
