As evening settles over Carlton Crescent, Nocturne comes to life. Tucked quietly within the house, our intimate cocktail bar carries the atmosphere of a modern speakeasy — where low lighting, polished glassware, and the gentle rhythm of jazz create a space designed for lingering. The music drifts softly through the room via our SONOS sound system, setting the tone for an evening that unfolds at its own pace. This is not a hurried bar. It is a place for conversation, for quiet celebration, and for cocktails prepared with confidence and precision. Elegant, intimate, and just a little indulgent.
At Nocturne, the drinks are as considered as the setting. Our cocktail menu brings together timeless classics and carefully crafted house favourites, prepared with premium spirits and fresh ingredients. Whether you favour the crisp elegance of a Martini, the warmth of a perfectly balanced Old Fashioned, or something a little more adventurous, each drink is created with an emphasis on quality and refinement. The result is simple: cocktails that are delicious, memorable — and reassuringly expensive.
For many guests, Nocturne becomes the natural final chapter of the day. A pre-dinner aperitif before stepping out into Southampton. A nightcap after returning from the theatre. Or simply a quiet glass of something exceptional while the music plays softly in the background. The bar’s intimate scale means every evening feels personal — more like a private lounge than a public bar. At Nocturne, the night does not rush. It lingers.
Alongside our cocktail menu, Nocturne offers a carefully curated selection of fine wines, premium whiskies, and exceptional spirits from around the world. Whether you are discovering something new or returning to a trusted favourite, our bar provides a setting where every glass is served with care — and enjoyed at leisure.
Guests of No.4 Carlton are invited to step inside and experience the quieter side of the evening. Because some of the best moments of a stay happen not in the room, but in the glow of a well-made drink, good music, and even better company.
