Always love eating their jajang myeon! People who are saying the staff are rude were probably rude themselves. I’ve dined here multiple times and have never thought their service was bad. Would highly recommend if you want to try some black bean noodles!

Great food, fast service, friendly staff! The jajangmyeon and jampong were really great and their kimchi was delicious as well.

Best jajangmyun in town. It’s al about the Chinese restaurants owned by Koreans. The dishes are epic and everything form the sweet and sour pork is ridiculous. We drive form Hawaii Kai or North Shore just to come here. Often imitated but never replicated. Trust Hunnerz Ko bloodline

Tiny hole in the wall place. Even though it says Chinese food, it's more like Korean food. Very traditional, authentic, food! Vegan/Vegetarian tip ????: order the jiajongmian plain with no meat/seafood. Yummy! …

Best blk bean noodle in town, so tasty. Love there spicy crispy chicken. Crunchy and moist at same time, very well balance spice, perfect paired with sochu and Swt/Sour shrimp.

Great food and fantastic service. You know it's going to be great when you are the only non-Asian in a Korean - Chinese place!

We usually have the jjajangmyeon here, which is very good. However, I remember my wife ordering a noodle soup for me once, which I really enjoyed. She doesn't refer to the menu, she just orders what she knows they have. I arrived here after work on Friday, hoping to get reacquainted with that mystery noodle soup. My first time ordering off the menu, so I picked the most likely candidate, "NOODLES WITH SEAFOOD & SOUP." I asked the server what the name of the soup was in Korean - "samseon-myeon." It seemed like what I had before, but I think my wife had ordered a separate, special sauce to mix in, which enhanced the flavor. I wasn't able to recreate my original experience, but it was still pretty good. For comparison, I ordered a second dish, "NOODLES WITH SPICY SOUP & SEAFOOD" - "jjamppong" in Korean. This was clearly not what I had before, but I enjoyed it even more than the samseon-myeon. The combination of noodles and seafood in the rich, savory broth needed no enhancement. This was a delicious, filling dinner accompanied by the usual side dishes and hot tea. The service was great, and I appreciated how they patiently answered my questions - even showing me how to write the names in Hangeul. https://www.facebook.com/share/p/9vszBEqPe56RkL25/?mibextid=oFDknk

Love coming to On Dong when I'm in the mood for some delicious jajangmyeon & tangsuyuk. Overall service is good. I wouldn't say the workers are super friendly, but what can you expect from a very small asian owned business . Wouldn't be the same without that type of service! The restaurant itself is small so I would recommend going early for lunch or dinner so you can avoid a wait.

Jjajangmyeon with tangsuyuk! Jjampong! The real deal! If you just watched Jjajangmyeon Rhapsody on Netflix and wonder "where on O'ahu can I try it while I save my $$$ for a trip to Korea?" then this is where you need to be. I found street parking on King Street- meter for an hour but dont worry, the food comes out fast. You're greeted with a friendly "Annyonghaseyo!" We came for the Jjajangmyeon but everyone was eating tge jjampong so decided to order that too. Banchan was onion with a dark sauce, pickled daikon and kimchee. Then our noodle dishes came. Then jjampong was seafoody and spicy in such a great blend and balance and rhe Jjajangmyeon was deeply flavorful and savory. The best part- the noodles! Chewy and delicious! I kept wanting to eat more but was so full- the portions are generous! The tangsuyuk was addicting- crispy, tart and sweet but not too sweet. I cant wait to go back!

This is my grandma's favorite black bean noodle (jjajangmyeon) spot on Oahu, and mine! This speaks volumes because my halmoni is very picky about what she likes, but once she finds a decent place she remains loyal for life. [Ambiance] On Dong is a Chinese-Korean fusion restaurant. There is a paid parking lot behind and metered street parking all around. Certain times of the day, and certain days, the street parking is free. I don't think there is a restroom inside the restaurant, but I suspect there's a public one nearby. [Service] Honestly, every single lady that works here is 100% fluent in Korean and in English. It's every Korean-American's dream. They are all very kind, hardworking and efficient. Each person anticipates your needs before you can even ask. I think they have the best customer service on the island of all the Korean businesses I've visited. Make sure you tip them at least 20%! They deserve that, and more! [Food] My boyfriend and I usually order the regular jjajangmyeon and kkanpunggi. My grandma particular enjoys their tangsuyuk. The banchan is good too. Love their kimchi! (Tip: pour some vinegar on the sweet onions to lessen the natural spice. Dip in the black bean sauce.) The meal also comes with hot tea--a sign of an authentic Asian restaurant. You can also ask for water! They usually have cups of ice water ready at the table. I will say that I ordered the jjamppong once or twice and it didn't have the kick I was looking for. Portions are always generous. Warning: You will likely experience food coma. I'm surprised I haven't reviewed this place before because I frequent often and have enjoyed each visit over the years I've lived on Oahu.
