Mildreds is a well-established vegan restaurant group with six locations across London, known for its creative, plant-based dishes and cult-like following among local diners.

Summary
Mildreds is one of London's most beloved restaurant groups. A cult following. A handful of exceptional central locations. A brand built over decades on bold, creative plant-based food that doesn't compromise on flavour or identity. As Mildreds looked to make paid media a core part of their growth strategy, NovaStory came on board as their dedicated paid media partner - bringing the commercial and technical expertise needed to scale with confidence. A strategy built around one clear objective: more covers, more revenue, measured with precision. Not just impressions. Not just link clicks. Seated guests and attributed revenue, accountable to the last penny.
Considerations
The brand wasn't the problem. Awareness wasn't the problem. Mildreds had built something genuinely special - a loyal, passionate audience in the tens of thousands that needed little convincing. The challenge was something more interesting: how do you grow beyond your already-converted base, in a fiercely competitive London dining market, without diluting the thing that made the brand worth loving in the first place?
The answer was to go incremental from the start. Rather than leaning on existing brand equity, we built campaigns designed to reach people who hadn't yet discovered Mildreds - flexitarians, occasion diners, food-lovers who'd rarely considered booking a plant-based restaurant but absolutely would. That meant building audience personas from scratch, applying highly segmented demographic targeting across paid search and social, and constructing an attribution infrastructure capable of connecting spend directly to reservation and revenue outcomes. All of it oriented around a single commercial truth: more covers, at a cost that makes business sense.
Efficiency wasn't a nice-to-have - it was non-negotiable. In a market where acquisition costs can spiral fast, we needed to grow reservation volumes without growing waste. That required disciplined campaign architecture, rigorous conversion tracking, and a clear-eyed view of what each channel was genuinely contributing - not just in traffic, but in seated guests and revenue.
Outcomes
The results speak for themselves. A 2,205% increase in attributed return on ad spend (ROAS) across paid search and social, with 20X+ average ROAS now consistent across every active paid channel. Paid attributed reservation volumes up +43%. Average conversion value from paid media up +34%. And an average cost per cover below £2 - exceptional efficiency for a multi-site London restaurant group operating in one of the world's most competitive dining markets.
Underpinning all of it is NovaStory's Revenue Attribution Modelling (RAM) framework - giving Mildreds complete clarity on which activity is driving revenue, what it costs to generate it, and where the greatest opportunity lies next. It's the kind of visibility that turns paid media from a cost centre into a genuine growth lever for hospitality groups. For Mildreds, that's exactly what our work with them has become.
