it's a Japanese style bar so...it's supposed to be a place you can sit and chat for a while... it's not the case, once you finished they ASK YOU TO LEAVE.
The food is great... one or two special dishes. Since it's suppose to be a Japanese style bar, make sure to research what you might like and try their alcohol.
No compare to the traditional style of Japanese bar that's warm and welcoming, DonDon have fast food type service, they don't welcome you to stay for drinks. You need to quickly finish your meal and leave. If you want to chat with your friends with a few drinks and enjoy the night, i suggest you go somewhere else.
