All-day dining in Cardiff Bay this Autumn.
Whatever brings you to Cardiff Bay this autumn, Cosy Club is open, warm and ready to welcome you. Come in from the cold for a Chocolate Chai and a Classic Breakfast, go all in on the Cosy Butcher’s Brunch, or make a weekend of it with bottomless brunch and a Bloody Mary.
Come back later for small plates; the Sharing Monkey Bread, made exclusively for Cosy Club by Baker Tom in Cornwall, is one to fight over. Then it’s on to slow-roasted pork belly with braised savoy cabbage, our Malvani chicken curry built on 15 aromatic spices, or a 28-day dry-aged rib-eye from Aubrey Allen, with a side of macaroni cheese because it’s that time of year. Vegan and gluten-free options run right through the menu, from crispy cauliflower to the chestnut mushroom curry.
Finish (or start!) with a cocktail, and you’ve got a good excuse to stay out of the weather a while longer at Cosy Club Cardiff Bay.
Marshmalloween is here
Grab a seasonal cocktail this Halloween. Our Toasted Marshmallow Martini blends vanilla vodka, crème de cacao, toasted marshmallow syrup, hot chocolate sauce and double cream. We top it with whipped cream and a toasted marshmallow.
For little monsters, there’s a Kids Hot Chocolate topped with marshmallows, here for half-term.
Available 19 October to 1 November only.
