PHAT Buns
Built different.
The brand
A UK fast-casual burger brand built around premium smash burgers, bold flavours and an unmistakable brand experience.
PHAT Buns was born in Leicester in 2019, after research into the US burger market and multiple trips to the United States that led to a unique beef blend.
Every burger is freshly smashed and cooked to order, served dine-in, takeaway and delivery, in stores designed around premium finishes, vibrant lighting and modern street-food culture.
From one site on Western Boulevard, PHAT Buns has grown into a national network with a franchise programme, and opened its first international site in Sharjah, UAE.
