Namaiki

Run by the same company that runs Yoroniku. The course dishes are pretty much the same as Yoroniku but are arranged with slightly less quality beef thus priced more reasonably. Definitely a great option for beef in this area. Good for a casual date dinner. Convenient location if you hang out in Akihabara. 

My rating: 5.0
