If you want to eat yakiniku, go to Jonetsu Hormone! @ All-you-can-eat Yakiniku Ikebukuro Sakaba Jonetsu Hormone

As the name suggests, Jonetsu Hormone is a restaurant that specializes in horumon.
In addition to rare horumon that you won’t see very often elsewhere, they also offer popular beef tongue and A5 Kuroge Wagyu beef.
The meat is grilled over a charcoal grill. It is popular because the far-infrared effect makes the meat plump and delicious.
