• Jollibee — famous for light, ultra‑crispy coating (order: Chickenjoy or Original Chicken Sandwich).
• Zaxby’s — regional chain known for crunchy breading and good sauce pairings.
• Bojangles — Southern‑style, crisp and well‑seasoned.
• Dave’s Hot Chicken — if you want spicy, very crispy Nashville‑style tenders/sandwich.
• Church’s or Popeyes rivals — big, crunchy pieces and classic Southern breading.

Quick tips to get maximum crispiness

• Eat soon after pickup (crispness falls as steam softens the crust).
• For extra crunch, order “extra crispy” or double‑breaded items when available.
• Tenders generally stay crispier than large fillets in a sandwich.
• If reheating at home, use a 375°F oven or air fryer for 8–12 minutes to restore crispness.

If you want, I can narrow this to chains near you or rank these by price, crunchiness, or availability in your city.
