Clark's Fish Camp, Not just seafood, they literally have the most wild game I have ever seen on a menu. Depending on whats on special I've seen python, gator, emu etc. Just the experience is worth the trip.
Anyone in the Amelia Island/Fernandina Beach area looking for the best breakfast spot in the state should try Mrs Carolyn’s in Fernandina Beach. Phenomenal spot. Cinnamon rolls the size of your head and it only gets better from there. Always packed and not a huge place, so probably not a good choice if you’re in a hurry.
If you want a huge breakfast try Maple St Biscuits Company. For an old fashion eggs place try Ellen's Kitchen (very cheap too). For donuts try Cinotti's Bakery.
