I went there twice with large group of friends in the VIP room.
Big tables, couches, water you can fill yourself, KTV and big TV screen.
You pretty much go in the front and order when you want, pay, then they deliver the food when it's ready.
Pricey for food and alcohol.
I tried the Chicken Katsu ramen. Dayum it was good. Always my Sapporo to accompany me during the night.
I had a great time singing and chatting.
The VIP room really makes a difference.
Staff is kind and always available at the front desk.
Strongly recommend for big group gathering.
