I got the Mango one in Holland+Barretts in Kingston, greater London on Saturday. They had the strawberry one too.
My pescatarian sister approved of it - she insisted to have the first slice because she says I wont be able to remember what cheesecake tastes like so cant judge. I liked it, and still have half left, but I'm not sure how often I'd pay £3.99 for it! Special occasions and major cravings only I guess.
