I'm trying to reserve for a restaurant in Tokyo that got stellar reviews (Ginza Kyubey). As such I need to reserve a long time in advance. The one site I found online that takes reservation and is in english in jpneazyEnglish is JPNEAZY.
I don't seem able to find reputable information on whether this site is safe and it requires payment upfront.
How does one go about checking whether this is safe and legit?
