Argento Steakhouse

You'll find Argento tucked right in the heart of the High Street, a proper grown-up space where they take their beef seriously. It's the kind of place you book for anniversaries or when you want to impress someone—leather, low lighting, the works—but it doesn't feel precious about it. The steaks are the main event here, charred how you actually want them, and the sides aren't an afterthought. It's become a reliable Southampton favourite precisely because it does one thing well and doesn't overcomplicate it.
