Cardiff’s food scene just got a major national shout-out! The definitive, diner-voted Harden’s Best UK Restaurants Guide 2026 has released its top picks, naming 12 brilliant capital city eateries. We are absolutely delighted that this year’s list features established favourites like Heathcock and Purple Poppadom, alongside fantastic newcomers like Canton’s Sonder and Llandaff’s Summer Palace. This recognition solidifies the message: Cardiff dining is living up to its capital city status.
The guide, now in its 35th year, is unique because it is based entirely on 30,000 reports from regular diners across the UK, not professional critics, making it a genuine reflection of customer satisfaction and loyalty.
The restaurant singled out for the coveted “outstanding” title among the 12 is Heaney’s on Romilly Road. Now in its seventh year, chef Tommy Heaney and partner Nikki’s spot has been celebrated by Harden’s reviewers as “a breath of fresh air in Cardiff”, where the “happy, bustling atmosphere” is a welcome contrast to fine-dining stuffiness.
Reviewers were quick to praise the “dead good value” tasting menu, decently priced set menus, and hearty Sunday lunch, cementing its place as an essential Cardiff eat. Tommy’s newest venture, Ember (a collaboration with former Heathcock chef David Killick), also secured a spot on the list, scoring a place in the Michelin Guide just months after opening.
Harden’s co-founder and editor, Peter Harden, commented that Cardiff’s restaurant scene was “living up” to the expectation of a capital city, a huge step up from when he had noted a “lack of ambition” three years ago. This progress is undeniable.
Let’s not forget the progress made this year: Gorse, run by Tom Waters, secured Cardiff’s first Michelin star earlier in 2025, less than a year after opening its doors! This wave of success shows the true passion and talent being poured into our city’s restaurants.
