Brothers Yousef and Ashram Al are offering the unique item at their newly-opened shop, Wagyu Bros, after spending 18 months perfecting the recipe.
Far from the usual kebab meat you might expect to find in your local takeaway, Wagyu Bros in Portsmouth, Hampshire, offers the luxury meat that comes from any of the four Japanese breeds of beef cattle.
Yousef, 26, explained he and his brother are 'both foodies' and like to experiment with high-quality ingredients at home.
"[We] turned it into something we want to serve the public because it was just too good. We wanted to go and do fast food, but the difference of using premium Wagyu beef," Yousef explained.
The Wagyu beef kebab is offered on Friday and Saturdays, when customers can get 200g of meat for £15 or 300g for £20. The brothers haven 15kg of the meat available each day, and as well as kebabs they also specialise in a variety of other Wagyu beef meals and vegetarian food.
Yousef said: "Our menu is very simple, we wanted to add another product and tested out loads of different things and kebab was just one of them, one of our favourite junk foods. It was one and a half years in the making, we tried, tested and wasted a lot of Wagyu beef, testing out loads of different recipes before finally, just only a few weeks ago we managed to perfect the recipe."
The 26-year-old said it takes 'about four hours' to make the kebab, and admitted they have 'invested thousands of pounds' into that product alone.
"It's completely fresh, so you're not getting yesterday's kebab. We just use wagyu, there are no other additives, and the only thing that we season it with is salt. So you're getting 100 percent meat," he continued.
"The taste is very different to the kebab that we're all used to, it tastes like actual meat with no aftertaste, and even the fat that comes off is a clean colour. One of our chefs is very experienced in kebab shops, and he's never seen the fat quite like it.
"People that are not aware of wagyu might think the prices are a bit extortionate, but for a foodie that knows what Wagyu beef is, it's the highest quality cow you can get. They understand that this is as affordable as we could make it."
The brothers believe they are the first in the UK to sell the Wagyu kebab, and as a result customers have travelled from all over the country to try the fancy meal.
Bilal Ahmed, from London, journeyed just for the kebab after seeing it on social media, saying he 'really enjoyed' the meal and wished the shop was located more locally to him.
"The quality of of the kebab is above the usual ones, it’s not processed unlike the others which you can tell they are quite processed and everything like that.
"It's lovely, 100 percent I’ll be having another as it’s very unique and definitely worth the £20 as the quality of the meat makes it really nice," Ahmed said.
