RAD Kitchen is Invercargill's deliberately hidden smashburger bar — the kind of place you find by following your nose down the back alleys until you spot the iconic pink door. Behind it: juicy burgers, a warm buzz of atmosphere, and the kind of word-of-mouth following that turned a backyard experiment into one of the city's most talked-about eats. As one satisfied customer put it: 'Pretty mean burger, juicy as, great atmosphere, worth it.'
The story is a local favourite. RAD began as a backyard burger operation — covered by Stuff as 'Invercargill's not-so-secret backyard burger bar' — before moving to its back-alley spot off Dee Street. It now operates as a trading name of Unconditional Love Ltd, serving smashburgers on a split-day schedule: lunch and dinner sessions Wednesday to Friday, one long session on Saturday, and delivery across Invercargill City via DeliverEasy and Uber Eats.
Beyond the grill, RAD runs its own online shop of house and small-batch goods: the best-selling RAD Sauce, the Apostle condiment range (Chocolate & Manuka Chipotle, Crispy Chilli Oil, Lavender & Rosemary Hot Honey), pickles and preserves, and drinks. Keep an eye on the events page and socials — rad people who wanna know stuff, after all.
There are burger bars, and then there is RAD Kitchen — a smashburger hideout tucked so deliberately out of sight that finding it is half the fun. The official directions, in the business's own words: follow your nose down the back alleys of Invercargill until you reach the iconic pink door. Roll on down, the sign-off urges, and don't be left hungry.
Behind that pink door is exactly what a neighbourhood burger bar should be: a hot grill, a warm buzz, and burgers people cross town for. One satisfied customer summed it up in a review the team is clearly proud of — 'Pretty mean burger, juicy as, great atmosphere, worth it.' In the south of New Zealand, that is close to a five-star citation.
RAD didn't begin in an alley. It began, like a lot of great food stories, in somebody's backyard — a home burger operation that got too popular to stay quiet. Local media caught on early; Stuff ran a feature welcoming readers to 'Invercargill's not-so-secret backyard burger bar,' and the nickname stuck even after the move. Today RAD Kitchen operates under Unconditional Love Ltd, and the journey from yard to alley is part of its identity rather than a footnote.
The location is central — Dee Street in Invercargill — but deliberately hidden, which gives every visit a small sense of occasion. First-timers get the thrill of the hunt; regulars get the smug satisfaction of knowing exactly where the pink door is. Either way, the reward on the other side is the same.
The headline act is the smashburger. It's a format built on confidence: beef smashed hard onto a screaming-hot griddle so the edges go crisp and lacy while the middle stays juicy, then stacked into something you'll struggle to eat elegantly. RAD leans fully into it, and customers respond with the kind of praise that can't be bought — 'juicy as' is about as glowing as reviews get down south.
Just as often, people mention the atmosphere alongside the food. That's the quiet trick of a place like this: the alley, the door, the room and the burger all add up to one experience, and it's why RAD has become one of Invercargill's most talked-about places to eat rather than just another quick dinner option.
Where RAD really sets itself apart is on the shelf next to the grill. Alongside the kitchen runs an online shop with three collections — sauces and condiments, pickles and preserves, and drinks — so the flavour doesn't have to stay at the burger bar.
The flagship is RAD Sauce, the shop's bestseller and, per its own pitch, the ultimate upgrade for your burger buddy. From there, the Apostle range reads like a calendar of flavour-forward saints: Saint Matthew pairs chocolate with manuka chipotle, Mary Magdalene is a crispy chilli oil, and Saint Valentine runs lavender and rosemary through a hot honey. They're small-batch releases that regularly sell out, which tells you how seriously this burger bar takes its condiments. The drinks list keeps it simple — a cold soda does the job — while the pickles and preserves collection rounds out the pantry.
RAD's hours are unusual, and knowing them is the difference between a pink-door photo and a locked one. Wednesday to Friday the kitchen runs a split day: 12pm to 2pm for lunch, closed in the afternoon, then 5pm to 8pm for dinner. Saturday is the marathon — noon straight through to 8pm. Sunday, Monday and Tuesday, the alley goes quiet.
If the timing doesn't work, the burgers come to you: RAD delivers across Invercargill City through DeliverEasy and Uber Eats, and both platforms carry the current menu, making them the best place to check exactly what's on the griddle this week. For everything else — new sauce drops, events, general goings-on — the team is active on Facebook, Instagram and TikTok, and the website's events page lists what's coming up.
RAD Kitchen is proof that a city doesn't need a big footprint to build a big reputation. One hidden door, one grill, a shelf of house-made sauces, and a community happy to walk down an alley for dinner. If you find yourself in Invercargill and hungry, do what the locals do: head for the back alleys, look for pink, and don't be left hungry.
