Charleston’s standout fish sandwich and the James Island spot behind it

Charleston’s seafood scene starts strong

Charleston is one of those places that feels welcoming the moment you arrive. Cobblestone streets, breezy waterfront views, and a deep love for food make it easy to relax and explore at your own pace.

Seafood plays a starring role here. The city sits close to rich coastal waters, and local cooks know exactly how to turn that fresh catch into memorable meals.

Among all the shrimp, oysters, and soups, one fish sandwich has quietly become a favorite among them. It comes from a James Island spot that locals take pride in.

Local favorite restaurant tucked on James Island

James Island sits just outside downtown Charleston, offering a more laid-back feel while still being close to the action. It is here that CudaCo. Seafood House has built a loyal following.

The restaurant opened in 2020 and quickly earned attention for its bold but thoughtful take on seafood. Locals appreciate that it feels neighborhood-friendly, not flashy or overdone.

Visitors often find it through word of mouth. Once they do, many leave talking about one standout item that keeps people coming back again and again.

Meet the minds behind CudaCo.

CudaCo. was founded by Chef Shaun Brian Sells and Chris John, a Charleston seafood distributor. Together, they combined cooking skills with deep knowledge of coastal fishing.

Their goal was simple but ambitious. Serve excellent seafood while respecting its origin and the fishermen who catch it. That philosophy shapes every part of the menu.

Chris John’s background helps connect the kitchen directly to fishermen in the region. This close relationship allows CudaCo. to serve fish that is fresh, responsibly sourced, and full of natural flavor.

Why seafood matters so much here

Charleston’s identity is closely tied to the ocean. For generations, fishing and coastal cooking have shaped daily life and family traditions across the region.

Local waters offer a diverse range of fish, including flounder, shrimp, oysters, and many lesser-known species that are rarely featured on typical menus. Cooks here know how to let those flavors shine.

At CudaCo., seafood is not treated as just another ingredient. It is the heart of the experience. Every dish reflects a respect for the sea and a desire to share its full variety with diners.

The famous Sandy fish sandwich

The Sandy fish sandwich is the item most people come to try. It’s built a strong reputation, and national food roundups have even singled it out as a top fish sandwich pick in South Carolina.

The sandwich features fried flounder layered with American cheese on a soft potato bun. Pickles, tartar sauce, and a touch of Crystal hot sauce bring everything together.

Nothing feels excessive or complicated. Each bite highlights the fish itself. That simplicity is exactly why many consider it one of the best fish sandwiches in the state of South Carolina.

A simple recipe done right

Part of Sandy’s appeal comes from restraint. Instead of piling on toppings, CudaCo. focuses on getting the basics just right.

The flounder is fresh and fried until crisp without being heavy. The bun is soft enough to hold everything together without stealing attention from the filling.

This careful balance allows the sandwich to feel both comforting and familiar while remaining special. It is the kind of meal that feels satisfying after one bite and memorable long after the plate is cleared.

A tuna twist for adventurous eaters

For those looking to try something different, CudaCo. offers an upgrade to the Sandy. Diners can swap the flounder for a rare tuna steak.

This option highlights the restaurant’s willingness to challenge expectations around seafood. Tuna served this way feels rich, clean, and surprisingly light, all within the same familiar sandwich build.

It is a small change that delivers a completely different experience. Many regulars enjoy switching between versions, depending on mood and what is freshest that day.

More sandwiches worth exploring

Sandy may be the star, but she is not alone. CudaCo.’s Po Boy offers several choices that highlight classic coastal flavors.

Guests can choose crispy oysters, shrimp, or scallops, each paired with a house-made remoulade. The result is hearty, flavorful, and deeply rooted in Southern seafood tradition.

These sandwiches demonstrate how the kitchen respects familiar favorites while keeping quality at the forefront. Each option feels carefully prepared, not rushed or mass-produced.

Fresh seafood beyond fried dishes

CudaCo. also shines when it comes to raw and lightly prepared seafood. The menu features poke bowls, crudo, and ceviche, all based on what is freshest.

The crudo is dressed with flying fish roe, olive oil, lime juice, and chilis, allowing the fish to stay front and center. The ceviche maintains a clean and bright appearance.

These dishes offer a lighter way to enjoy the ocean’s flavors. They also show the range of techniques the kitchen uses with confidence and care.

Classic options for every appetite

Not everyone comes in the mood for something raw. CudaCo. offers plenty of traditional choices that feel familiar and comforting.

Raw and baked oysters are popular, along with steamed mussels and clams. Guests can also choose their own fish for a custom fry.

A smoked seafood chowder rounds out the menu, providing warmth and depth. Together, these dishes make the restaurant approachable for all ages and tastes.

Sustainability at the core

Sustainability is not just a buzzword at CudaCo. It is central to the restaurant’s daily operations. The raw seafood case often includes fish sourced through direct relationships with local fishermen, alongside other trusted suppliers.

Some of these species are less common on American menus but abundant in nearby waters. By highlighting a wider range of species and using more of each fish, CudaCo. aims to promote a more thoughtful, lower-waste approach to eating seafood.

Guests also learn that great seafood extends far beyond the few fish with which most people are already familiar.

Learning from the local waters

Co-founder Chris John often speaks about the region’s waters as a living aquarium. The variety available is remarkable and often overlooked.

CudaCo. embraces this diversity, using the menu as a way to educate without lecturing. Diners discover new fish simply by enjoying a great meal.

This approach builds appreciation for local ecosystems and the people who work on the water. It also helps preserve seafood traditions for future generations.
