Back in March, Marceline held a Top of the Croques competition where various chefs placed their own spin on the croque monsieur, with Ana Da Costa paying tribute to her Portuguese heritage with a nod to the bifana, thatched with shoestring fries. Another Portuguese restaurant, arguably the first of the new-wave, Bar Douro, also puts bifanas on from time-to-time. They are a solid option and at their last outing cost less than a tenner.
