I had a Fantastic time ! Ryohei and Toshi were very helpful and always tried to help even if they could not understand. Their English is very good which did come in handy. If you're also looking to learn about Japan and it's culture you can ask them . MY FAVORITE thing about the place was that it is an OTAKU HEAVEN . They have so many different Manga Books and a PS4 and more. It is very close to Otorii station and there are many Restaurants within a 300 meter radius. I highly recommend this place if you're landing at Haneda Airport, since it's only 2 stations away
