OK. You should know some things first.

1. This is an all ages cafe. There was definitely a family with a 7 year old having a blast there.
2. This is an innocent type place. If you were seeking something more... adult oriented- This ain't it.
3. This is a very high-energy environment. We arrived after 10 hours exploring the city and were drained / not very invested in the experience. 2/3 of our party thought we were going to be like pampered and spoiled during our visit. NOT the case. There were seriously about... 9-14 maids working. For maybe 7-10 groups. And I can't put into words how little I felt we were interacted with by them. I'd often look up and see a group of 6 swarmed around a party of 2. We felt ignored and neglected.
4. Due to our low energy, I can only assume that was why we WERE neglected.
5. There was a HUGE language barrier. I often didn't understand what they were trying to say or get me to participate in. Like, we read the rules but the maids would often come up and try and make us say words or chants over food items that weren't easy to repeat or have a pronunciation in English to help me try and participate. You must say "Meow Meow" to your maid.
6. We only ordered ice cream and 2 cocktails. We also bought a bazooka. We paid and stayed for the full hour, but I'll say we felt highly stressed out as we realized that THEY were trying to keep us there longer than an hour, which would force us to pay for a 2nd hour. But the amount of time it took for the ice cream and cocktail to arrive... unacceptable. Over 30mins. The buddy received his bazooka - which they ONLY let you have for a stage performance took almost an hour to be delivered to our table. Which we were told we could not take out with us, and since we didn't want to stay for that 2nd hour charge, increased our anxiety.
7. No pics or videos allowed of the maids. Like, "What?" I PAID to enter, but I have to pay an extra fee to be able to record or take pics??? Imagine paying to go Disney, and then Mickey Mouse wants you to fork over an extra $20 for a pic.

So here's the takeaway: Be prepared to pay for at least an hour. Slow food and service. If you're not fluent in japanese - this could easily be a disappointment. If you're tired or have low energy - just skip this until you have the energy/endurance to stay a full hour and keep a smile on your face. The food is cute, I just feel like you can find the "cute" food almost anywhere else where you're not forced to pay by the hour and won't have an extreme wait. Like, I truthfully feel like I saw all other tables, including those who arrived after us, get served before us.

To me, this is a skippable experience. I love DDR music, but after an hour, I could go the rest of my life without that high energy, high-pitched singing. Add in the fact that i just felt like a very neglected guest for well, not memorable food... at best, this is a 3-star experience, at worst a 1. If you ARE looking for a bizarre, high-energy experience. Look no further. But beware the customer service and language barrier.
