I had this as lunch. Katsu was good. But indeed not the best. I think the good side is they have variety of price choices. Almost everything on the menu was around £6! I also ordered miso ramen and honestly the soup was too bland and had weak flavour. My friend who had tonkotsu asked for salt and chilli powder. P.S. #1 the chashu (pork) is more like Chinese char siu style (harder and nm fat) #2 ramen comes with bean sprout The restaurant was semi self-service style. Do not expect much. Not bad but not excellent either
