Their signature, 'IE kei ramen' is thick noodles with strong tonkotsu soup from Yokohama. I just had authentic hakata ramen at ikkosha last week so I can't stop comparing... ikkosha's ramen was way better for me. I thought it would be too heavy and ordered small bowl. I regretted immediately. it's tiny and 180B. The soup was very salty... it's not my cup of tea.
