Don't mention the plant-based meat at Flave

The key thing about Flave, a new diner-style restaurant five minutes from Bondi Beach, is that the food is excellent. The menu's entirely plant-based origins won't cross your mind if no one mentions it.

There are no big signs advertising each dish's non-animal origins and people left, right and centre in this bright-and-breezy lunch and dinner spot are wolfing down mushroom-based brisket, vegie chorizo bits and burgers made from soy protein with the same gusto as any beef-lover.

Diehard meat fans could order the Classic Flave Burger, or its upscaled counterpart the Epic Flave, and find themselves swooning over a chunky gluten-free, protein-rich, soy-based Buds patty, maple-glazed "bacon", vegan cheese, battered onion rings, pickles, barbecue sauce and a whacking great roasted mushroom, despite any preconceptions of vegan food. I'll vouch for it.

Sitting in a sunny, cushioned booth in the heart of Bondi eating Flave's luscious, melty cheeseburger with smoky sauce and hot burger juice dribbling down your fingers is ideal stuff. And not just because it's ethically and environmentally sound.

Founded by husband-and-wife team Samantha and Stuart Cook, Flave opened in December nearly six years after a bacterial infection on the pair's honeymoon in Costa Rica transformed their diet.

"I was airlifted to hospital due to something I ate and I had a severe bacterial infection," Samantha says. "By the time I arrived, my heart was going into secondary complications."

She recovered but the life-saving broad-spectrum antibiotics stripped her stomach's microbiome.

A doctor's suggestion of a plant-based diet led to blooming health but eating out uncovered the sparse range of non-animal options in restaurants.

"It was either a leafy salad or your typical carb-heavy pasta Napoletana," Samantha says. "There wasn't something in between that was just as amazing as everybody else's food."

Stuart, a formerly chief executive of Mexican-inspired food franchise Zambrero, and Samantha, former chief executive of charity One Disease at a Time, imagined their own restaurant and brought in executive chef Scott Findlay – who has trained under Gordon Ramsay, has cooked for Beyonce, Elton John and Rod Stewart and was private chef to Paul McCartney.

Findlay created a flavour-focused plant-based menu, ranging from burgers to bowls including a Southern Fry burger with a "baconnaise"-laced cauliflower steak, rendang "beef" curry, Italian "meatballs", spicy Jamaican jerk "chicken" and an acai smoothie bowl piled with tropical fruit and soft serve.

To a view of tanned, barely clothed types wandering by outside, we finish the burger and start the So Su Me Bowl, a landscaped vegan hillock mirroring a tuna tartare poke bowl.

Beautiful to behold, it is an unexpected tastebud ally with spinach, carrot, cucumber, quinoa, rice, pickled ginger, edamame and avocado seasoned with Japanese togarashi spice and miso ponzu dressing and served with a crunchy nori tempura.

Also excellent are the Japancini balls, four crunchy golden orbs made from crushed edamame, nori, ginger and a chilli and miso glaze, served with pickled ginger and wasabi aioli.

Paired with crunchy hot chips and a Total Tropic smoothie blending orange, pineapple mango, banana, ginger, turmeric and carrot, the bikini-ed but anxiously masked world outside Flave's neon, wood and smoothly concrete-edged plant-based haven is forgotten.

We polish off a luscious brownie made from sweet potato and almonds, and a frozen acai soft serve made from beetroot, orange and carrot as the sun sets.

The Cooks' goal in the next 10 years is opening more than 1000 Flave outlets across Australia, the US and China, that appeal to every palate, meat-eating or not.

"We had Argentinians come in recently and not realise it was plant-based," Stuart says. "They said, 'Get out of town, we know our meat'. And we said, 'Yeah, that's not chicken, that's cauliflower'."
