"Catalyst’s menu switches up regularly, but its magnificent sandwiches always remain at the Holborn cafe. A classic bacon number wedged between doorstop slices of pain de mie bread is a ketchup-sodden breakfast of the traditionally British variety, with a little onion and dill relish thrown in as well. But there are other things too: a homemade take on a familiar fish filet sandwich, only this one features chunky goujons big enough to make Captain Birdseye blush, a tangy homemade coleslaw, and a creamy slice of american cheese." - jake missing, rianne shlebak, sinead cranna
