Keks is one of the most popular cakes in Poland (a bit like an Old English fruitcake), and you can expect to find a very good slice of the stuff waiting for you here. You should also expect a top Old Town square location, but one which comes without the usual premiums. No, no rip-off prices here, just a gorgeous, eccentric little cafe of the old school, the kind of place you want to hug and take home to your mother.
