Big Tuna Raw Bar in Charleston: Fresh Seafood and Cocktails on King Street

What Big Tuna Raw Bar Offers

Big Tuna Raw Bar is a seafood-focused restaurant and bar on King Street in Charleston's downtown district, known for raw oysters, shrimp, and fish served at a raw bar counter, plus cooked seafood dishes and cocktails. The space has the casual energy of a working seafood bar rather than fine dining—you can eat at the counter watching the shuckers work, or sit at tables throughout the restaurant. The menu changes based on what's available from local and regional suppliers, so what's fresh on a Tuesday may differ by Friday.

The raw bar is the centerpiece: oysters arrive daily and are shucked to order, served on ice with cocktail sauce, hot sauce, and mignonette. Beyond oysters, you'll find chilled shrimp, crab, and whatever raw fish the kitchen has sourced that day. The cooked side of the menu includes fried seafood, grilled fish, shrimp and grits, and other Low Country preparations. The bar stocks spirits, wine, and beer, with cocktails that lean toward classics and house drinks built around seafood pairings.

Location and Hours

Big Tuna Raw Bar sits on King Street in downtown Charleston, in the heart of the restaurant and retail district. King Street runs north-south through the center of the historic district and is walkable from most downtown hotels, parking garages, and the waterfront. Street parking is available but often full during peak hours; several paid lots are within a block.

Hours vary by season and day of the week. The restaurant typically opens for lunch and stays open through dinner service, but you should confirm current hours before visiting, as they may shift with tourism patterns or staffing. Call ahead or check their social media for holiday hours or any temporary closures.

What to Order and What to Expect

Start at the raw bar if you want oysters. Ask the shucker what's in that day—they can tell you where each oyster comes from and what it tastes like. Oysters from different waters have different brine levels and flavors, and the staff can guide you toward what you prefer. If you're new to raw oysters, order a small selection (three to six) rather than a full dozen, and try them plain first before adding sauce.

Beyond oysters, the raw bar usually has chilled shrimp and crab. The cooked menu includes fried oysters, fried shrimp, fish of the day (often grilled or blackened), shrimp and grits, and sides like coleslaw, hushpuppies, and fries. Portion sizes are generous. Cocktails are made to order, and the bartenders can suggest pairings if you ask. Beer and wine are also available, and a cold beer is a natural pairing with raw oysters.

Expect a casual atmosphere and a wait during peak times—lunch around noon and dinner after 6 p.m., especially on weekends. The bar fills up quickly, and tables may have a short wait. Takeout is available for raw oysters and cooked items if you want to eat elsewhere.

Pricing and Payment

Raw oysters are typically priced per oyster or by the half-dozen and dozen, with prices varying based on the type and source. Cooked entrees run in the mid-range for Charleston seafood restaurants. Cocktails are standard bar pricing. The restaurant accepts cash and cards.

If you're budget-conscious, ordering a few oysters and a beer or soft drink can be a lighter, less expensive meal than a full entree. Happy hour specials may be available during off-peak times—ask when you arrive or check their social media for current promotions.

Parking and Getting There

King Street has metered street parking, though spots fill quickly during the day and on weekends. Several paid parking garages are within one to two blocks: the Saks Parking Garage, the King Street Parking Garage, and others in the downtown core. Parking rates vary but typically run a few dollars per hour or a flat rate for the day.

If you're using ride-share, ask the driver to drop you on King Street near the restaurant. Public transit in Charleston is limited, but CARTA buses serve downtown; check the route map if you're coming from outside the historic district. Many visitors walk to Big Tuna from nearby hotels or attractions.

When to Go and What to Bring

Lunch is quieter than dinner, so if you prefer a less crowded experience, go between 11:30 a.m. and 1 p.m. Dinner service gets busy, especially Friday and Saturday evenings. Weekday afternoons are also a good time to visit if you want to chat with the shuckers or get personalized recommendations without a line behind you.

Dress is casual—no reservations or dress code. Bring cash if you prefer it, though cards are accepted. If you're sensitive to seafood smells or raw preparations, be aware that a raw bar has a strong briny smell that permeates the space. The restaurant can be loud during peak hours.

Nearby Attractions and Dining

King Street is surrounded by other restaurants, shops, and galleries. The historic district is walkable from Big Tuna, so you can combine a meal here with browsing nearby boutiques, visiting the Gibbes Museum of Art, or walking toward the waterfront and the Battery. If you're exploring downtown for the day, Big Tuna works well as a lunch or dinner stop in the middle of other activities.

Other seafood options are nearby if you want to compare, but Big Tuna's raw bar focus and casual counter service make it distinct from sit-down seafood restaurants in the area. The location on King Street also means you're close to coffee shops, dessert spots, and bars if you want to extend your outing.

Frequently Asked Questions

Do I need a reservation?

Big Tuna Raw Bar typically operates on a first-come, first-served basis and does not take reservations. Arrive early during peak times (lunch around noon, dinner after 6 p.m.) to avoid a wait, or call ahead to ask how busy they are at that moment.

Are the oysters safe to eat raw?

Raw oysters from reputable suppliers are safe for most people. They come from regulated waters and are handled according to food safety standards. If you have a compromised immune system, are pregnant, or have shellfish allergies, consult your doctor before eating raw oysters. The restaurant staff can tell you where each oyster comes from if you have concerns.

What if I don't like raw oysters?

The cooked menu has plenty of options: fried oysters, fried shrimp, grilled fish, shrimp and grits, and other seafood dishes. You don't have to order from the raw bar. Ask the staff what's good that day, and they can recommend cooked items based on what's fresh.

Can I order oysters to go?

Yes, Big Tuna offers takeout for raw oysters and cooked items. Call ahead if you want a large order, so they can have it ready when you arrive. Oysters travel well in a container with ice, and you can eat them within a few hours of purchase.

What's the difference between the oyster types on the menu?

Oysters vary by where they're grown—different waters produce different flavors, sizes, and shell shapes. The shucker can explain the differences and help you choose based on whether you prefer briny, sweet, or buttery flavors. Trying a few types is a good way to discover what you like.
