Located on the Clerkenwell side of Old Street, Monohon serves just six types of ramen, including three soup-less ones, one of which is served chilled. The Spicy Tonkotsu – creamy pork bone broth with thin noodles, bean sprouts, spring onions, slow cooked pork belly and spicy miso pork mince – is a winner and you can customise it to your liking, choosing level of spice, how hard you want your noodles and how big you want the bowl to be. Slurping = essential.
