I recently went to the Eorzea FFXIV cafe in Akihabara, Japan.
It was awesome!
Many people have asked how to book the reservations online, so here are the step-by-step instructions:
1. Go to this website: Eorzea Cafe Online
10. Since I don't want to book reservations again I can't screencap anything past this point (if anyone wants to send me screenshots I'd be happy to add them). The next screen is asking you to confirm all your details. Once you confirm, you'll have to go to a Lawson convenience store and use their ticket machine to print out your ticket(s). Remember, if you made a reservation exactly like in this walkthrough, you will get ONE ticket that works for FOUR people. Reserving online like this, will also get you a free drink at the cafe!
Enjoy your awesome experience and delicious food! :D
