To be honest, my score is 1.5 star. Because of friendly staff there, I put 0.5 on DonDon. Otherwise, it's 1.0. Personally, I won't come back by myself.
I know I'm tend to be hard on Japanese restaurants since I'm Japanese, BUT...
1. They don't bring food in manner. Please don't bring Kushi-age(fried stick meat and vegetable AFTER we had dessert!
2. Since I am almost vegetarian, I didn't try all of dishes which my friends ordered (meat, seafood etc.), but some. Those few dishes were just OK kinds They were very salty.
3. I doubted about quality of the ingredients there - plus, I heard a strange story about them from one of my Japanese friends afterwards.
Atmosphere wise, it's fun. I may come back DonDon for my friends who love Sake or sharing the fun atmosphere. But I won't be there with hungry stomach. That's for sure.
