Dark Luxury Restaurant: Dark Stone, Velvet, and Metallic Sheen

Design a restaurant in a dark luxurious register, rich rather than austere. Show a deeply veined dark marble — a black with dramatic white and gold veining — used generously on the bar mass, the tabletops and a full feature wall, bookmatched so the veining forms a symmetrical figure. Detail the walls in a dark stained fluted timber with a satin sheen, and the ceiling in a deep charcoal with a subtle lacquered reflection. Show the seating in a rich velvet — deep emerald or petrol blue — with a slim antique brass frame and piping. Detail every metal as antique brass with a soft unlacquered patina: the foot rail, the door pulls, the table edges, the sconce bodies. Show the lighting as low, warm and jewel-like: small directional spots picking out each table, concealed light grazing the fluted timber, and the bar back lit from within. Detail glassware and cutlery catching points of light. Show evening with a full elegant room. Photorealistic, opulent, black marble and brass, eye-level view.
