It is really hard to beat Liar's Club next to Stinky's Fish Camp. Their Fisherman's Breakfast is filling and always wonderfully prepared. It is the only place we now go for breakfast on 30A.
Our favorite breakfast in SoWal was Red Bar, but they don't serve breakfast any more.
For the best breakfast food, it's Stinky's by far. But the best dishes on the menu aren't something you could eat for breakfast every day -- so rich and yummy and calorific.
We love Hibiscus. It's a light breakfast that is healthy.
We just discovered breakfast at Flip-Flops. I love the bacon sandwich without mayo.
If I want fried eggs over easy, we go to Great Southern. That's the only place on 30A I know of to get them served that way (now that Red Bar doesn't serve breakfast).
As many have already noted, Stinky's Liar's Club rules for breakfast (especially since the Red Bar quit serving breakfast). Others to consider - Cowgirl Kitchen, Flip Flops and Seagrove Coyote all are great for a quick meal or to carry out.
