There’s something magical about seafood served a few blocks inland, and Mac’s Raw Bar in Marietta Square has made it work exquisitely. This lively oyster‑and‑seafood spot brings a coastal vibe to Cobb County, spotlighting sustainably sourced oysters, shrimp, crab, and other treasures of Georgia’s rivers, Gulf Coast, and Atlantic harvests. It’s a standout among Marietta’s dining scene (macsrawbar.com).

At Mac’s, the raw bar truly steals the show. Their selection of oysters rotates daily, delivered fresh from hand‑picked oyster farms and served with classic mignonette, cocktail sauce, and housemade hot sauce. Reviews uniformly rave: “variety of fresh oysters,” “jumbo shrimp cocktail,” and “broiled seafood platter” often cited as signature dishes (macsrawbar.com, ajc, OpenTable).

Beyond oysters, dishes like the jumbo shrimp cocktail, broiled seafood platters, crispy Brunswick shrimp, and delicate crab dip receive consistent praise from diners. Yelp reviews mention buttery dirty rice, succulent seafood, and excellent service from the kitchen and front of house (Yelp).

Just steps from the historic courthouse square, Mac’s chooses simplicity over showiness—letting the seafood shine. The menu emphasizes clean, seasonal preparations, and rotating daily specials—from crispy shrimp and grits to blackened redfish étouffée and brunch baskets featuring deviled crab or redfish baskets. Their coastal‑crafted philosophy shines through, with a wine list curated to pair beautifully with every dish (macsrawbar.com).

Open every day from 11 am, Mac’s offers dinner service until 10 pm on most nights and extends to 11 pm on Fridays and Saturdays. Patrons can dine casual, enjoy cocktails, or grab to‑go orders, making it a versatile destination on Marietta Square (macsrawbar.com).

Major local sources like the Atlanta Journal‑Constitution praise the atmosphere as convivial and energetic, with servers fluent in menu details and keen to recommend pairings—even noting a central oyster‑shucking station adding to the vibrant ambiance. While a few early critiques flagged inconsistencies (some oysters running low mid‑week or certain dishes under‑seasoned), follow‑ups suggest the kitchen has refined execution over time (ajc).

“We had the market platters … Lobster, shrimp and scallops over buttery dirty rice. The service was excellent.” (MapQuest, Yelp)
 Another noted:
