Maybe it’s just them doing their own version of the Dirty Bun; the Dirty Croissant here lacks the dirtiness and the flavour oomph however. Not sure if they deliberately left out the the fillings here, but the croissant is pretty much like any other croissants without cream/chocolate fillings within; just topped off with cocoa powder and a slight drizzle of chocolate sauce topped with hazelnuts. The croissant is buttery, yet with a bittersweet chocolate flavour without being overly sweet. Sure, perhaps the lack of fillings is the reason why they name in the Dirty Croissant instead of Dirty Bread, but it does make it feel like it’s missing of something.
