There are already a few 24-hour McDonald’s restaurants in London, and it looks like the Leicetser Square branch is about to join them. McDonald’s Leicester Square has been granted a license to operate 24 hours a day. The Leicester Square branch is considered London’s flagship, and apparently largest, McDonald’s. McDonald’s is currently going through its hot honey moment, serving a Hot Honey McCrispy burger as well as a hot honey dip — intended to be served with its new mozzarella dippers. There’s even a hot honey mini McFlurry.
