Lucy Williams is enjoying an iced strawberry matcha after going with her sister to her niece's first-ever haircut.
"I feel like a strawberry matcha is a coming out with your sister thing, rather than an everyday thing," she says.
But you can't get an iced strawberry matcha - or any kind of matcha at Costa Coffee.
Lucy is at Blank Street Coffee where a rainbow array of matcha drinks have gained the chain a cult following, including celebrity fans Mollie-Mae Hague and Sabrina Carpenter.
Lucy drinks coffee at home every day, but buys a barista-made cup for when she wants a treat.
