Mr B's Seafood House: Fresh Catch and Local Favorites in Charleston

What Mr B's Seafood House Offers

Mr B's Seafood House is a working seafood market and restaurant in Charleston's historic district, where you can buy fresh fish and shellfish to cook at home or eat prepared dishes on-site. The market side stocks local catch—shrimp, flounder, grouper, and seasonal varieties—alongside frozen options and prepared seafood salads. The restaurant side serves lunch and dinner in a casual dining room, with a menu built around what came in that morning.

The business has operated in Charleston for decades and draws both locals stocking their kitchens and visitors looking for a straightforward seafood meal without the fine-dining markup. You'll find the market counter at the front, where staff can tell you what's fresh that day and how to cook it, and the dining area behind, where you order at the counter and eat at simple tables.

Key Takeaways

• Mr B's operates as both a retail seafood market and a casual restaurant, so you can buy raw fish to take home or order prepared plates to eat there.
• The menu changes based on what local boats bring in, so the catch available today may differ from what you'll find next week.
• Prices at the market counter are typically lower than restaurant plates for the same fish, since you're buying wholesale rather than prepared.
• The restaurant does not take reservations, so arrive early during peak lunch and dinner hours if you want a table without waiting.

The Market Counter and What to Expect

The seafood market counter is where Mr B's sources its restaurant supply and sells directly to home cooks. You'll see ice-packed cases of shrimp in various sizes, whole fish on display, and fillets cut to order. Staff can tell you the source of the catch—whether it came from local waters or was brought in frozen—and can answer questions about how to prepare unfamiliar species.

Prices vary by what's in season and what the boats landed that day. Shrimp, the most consistent item, ranges in size from small salad shrimp to large Gulf whites. Flounder and grouper are common when in season, and the market sometimes carries less familiar options like triggerfish or vermilion snapper depending on the catch. If you're unsure what to buy or how to cook it, the staff can suggest preparations and portion sizes for your party.

The market is cash-friendly but also takes cards. Hours vary seasonally, so calling ahead is wise if you're making a special trip for a specific fish.

The Restaurant Side: Casual Dining and Daily Specials

The dining room serves lunch and dinner with a menu that shifts based on the market's inventory. You'll find fried platters—shrimp, fish, scallops—served with hushpuppies, coleslaw, and your choice of side. Grilled options are available for those avoiding fried food, and the kitchen can usually prepare fish simply with butter and lemon if you ask.

Crab cakes, shrimp salad, and fish sandwiches are regular offerings. Soups and chowders rotate, and the restaurant sometimes features regional dishes like she-crab soup when crab roe is in season. Prices are moderate—most entrees fall in the range you'd pay at a casual neighborhood restaurant rather than a tourist-focused establishment.

Service is counter-order style: you step up to the register, order and pay, then find a seat and wait for your number to be called. The dining room is simple and unpretentious, with the focus on the food rather than ambiance. No reservations are taken, so timing matters during peak hours.

Location and Hours in Charleston's Historic District

Mr B's sits on King Street in downtown Charleston, within walking distance of the Market Hall and other historic attractions. The storefront is modest and easy to miss if you're not looking for it, but the smell of fresh seafood and the ice-packed window displays make it recognizable once you know what to look for.

Hours typically run from late morning through early evening, with the market closing earlier than the restaurant on most days. Seasonal hours shift with tourist traffic and the fishing calendar, so checking ahead by phone before your visit prevents disappointment. The restaurant is closed on Sundays and Mondays, a common pattern for Charleston seafood houses.

Buying Fish to Cook at Home

If you're staying in a rental with a kitchen or cooking at a friend's house, the market counter is a practical way to get fresh local fish without the markup of a grocery store. You can buy a single fillet or a whole fish, and the staff will clean and fillet on request. Prices are typically lower than supermarket seafood counters because Mr B's buys in volume and sells quickly.

Ask the staff how fresh the fish is and when it arrived. Local catch landed that morning will keep longer and taste better than fish that's been on ice for several days. If you're unfamiliar with a species, ask how it cooks—some fish are better grilled, others better fried or poached—and whether it's mild or has a stronger flavor.

Why Mr B's Matters in Charleston's Food Culture

Mr B's represents an older model of Charleston seafood retail: a working market that also feeds people, rather than a restaurant that happens to sell fish. The business depends on the daily catch and local fishing patterns, which means the menu is genuinely seasonal in a way that most restaurants are not. This connection to the water and the boats is part of what draws locals and visitors who want to eat what Charleston's coast actually produces.

The casual, no-frills approach also reflects Charleston's working waterfront heritage. You're not paying for décor or service theater; you're paying for fresh fish and straightforward cooking. For visitors interested in how Charlestonians actually eat—not how restaurants present Charleston to tourists—Mr B's is a useful stop.

Frequently Asked Questions

Can I buy just one or two fillets, or do I have to buy a whole fish?

The market sells by the pound and will fillet fish to order, so you can buy as little as a single fillet. Pricing is the same whether you buy one or several, and the staff can portion it however you need for your meal.

What's the difference between the shrimp sizes I see in the case?

Shrimp are sold by count per pound—smaller shrimp have more per pound, larger ones have fewer. Small salad shrimp are good for appetizers or mixed into dishes; medium shrimp work for most cooking; large Gulf whites are best for grilling or frying whole. The staff can tell you the count and suggest which size suits your recipe.

Do I need to make a reservation for the restaurant?

No, Mr B's operates on a first-come, first-served basis with no reservations. Lunch and dinner rushes can mean a wait during peak hours, so arriving early or going at off-peak times (mid-afternoon or early evening) usually means shorter waits.

What if I don't recognize a fish on display—how do I know if it's good?

Ask the staff. They can tell you what it tastes like, how to cook it, and whether it's a good value that day. They can also suggest substitutes if a fish you wanted isn't available or if you want something milder or more flavorful than what you were planning.

Is Mr B's cash only?

No, the market and restaurant both take cards and cash. However, having cash can be useful since some seafood markets offer small discounts for cash purchases, though Mr B's pricing is consistent either way.
