Just had my first spicy grilled chicken sandwich from CFA. It was good. Not as good as their fried, but better than their regular grilled.
My secret combination that I think combines the best of all of CFA: Regular fried sandwich with pepperjack cheese and cilantro lime sauce. Or switch out the lime sauce with honey bbq. Combo that with waffle fries dipped in CFA sauce and a Sprite with extra lemon wedges (no joke, try it with extra lemon. it's like a brand new drink.)
