We came here after shopping at H Mart because we were hungry and wanted something quick to eat. The cashier was friendly and hardworking, and our food came out in a reasonable amount of time. It wasn't a busy time of day, so there were no other customers besides us. We ordered Set #1 and Set #2. Overall, the food was good, and the noodles were especially chewy and delicious. The only downside was that the jjampong broth was a little lacking in depth of flavor, which was slightly disappointing. Still, it's a convenient place to stop for a quick meal while shopping. We'll definitely come back again next time we're at H Mart! read more

Was really hoping this would be it for good Korean Chinese restaurant in Diamond Bar area. Unfortunately it fell flat and the search continues. The jajangmyeon sauce was decent. The noodles were different from the typical jajangmyeon noodles. They were thicker more like udon noodles. The tangsuyook was subpar, meat was tough and batter wasn't as light/crispy (however I did have this to go so that may have impacted the texture). Shrimp fried rice was mostly rice and came with 5 shrimp. Typically banchan such as radish, kimchi, or onion are included but there were no side dishes with my order. It's convenient to order since it's inside the super Hmart but if you want good Korean Chinese, you'll need to go elsewhere. read more

TLDR: very thick hand pulled noodles. good prices. appreciate the combo so you can get the tangsuyook as a side. would love to see a kkanpung shrimp! Located in an Hmart food court. The flavors are decent, considering there's no good Korean-Chinese spot in the area. Not sure if I'll return bc I live far away but if you're in the area, try it out! read more

Red Dragon - much better after eating some jjampong - Noodles Near Me - Diamond Bar, California

It is located inside a H mart. We ordered a jjambbong combo (jjambbong + sweet & sour pork) and jja jang myeon (not pictured) and shared between two of us and it was a good size for two people. Jjamppong - I was very surprised how good it was. My husband thought the same It is one of the best jjamppongs I had in US. Definitely recommended! Sweet and sour pork - another recommended menu. The outside is so crispy yet also chewy. Jja jang myeon - compared to other dishes, this one was just meh. I probably won't order it again. I think it lacks a bit of flavor Enough parking in the plaza. There are seats available for the food court yet can get busy during peak times read more

Its been awhile since I've been to the H Mart in Diamond Bar since the opening of the H Mart in Chino Hills. I was hungry and had a few snacks at the food court but the Spicy Beef Soup with Rice at Red Dragon caught my eye, so I said to myself I need to try it, so I ordered it for take out. Oh Boy! I was glad I did. I got home it was still hot but still wanted it a bit warmer. I took a sip of the broth and I was OMG this is gonna be good. The beef was tender and melted in your mouth, with a spoonful of the right amount of rice a broth with the radish on side it was yummy in the tummy. I'll be sure to take pictures next time. Until then, Enjoy! read more

Red Dragon *September 4, 2025 *6:30pm- Thursday *4.5 Stars Environment: *Large Parking Lot *Quick Service *Located Inside H-Mart Food/Drink: *Jja Jang Myeon My sister and I were shopping at H-Mart and stumbled across Red Dragon in the small food court. We've tried some of the other spots before, but this was our first time here. Noticed quite a few other customers ordering the Jja Jang Myeon, so we decided to try it as well and got it to go. The service was quick, and the portion was much larger than expected--definitely enough to share. The noodles were chewy and the sauce flavorful, though a little salty for my taste. Overall, it was still delicious, and I'm looking forward to coming back to try some of their other dishes. read more

For fast casual, I would have to give them a thumbs up. Jajangmeon was really tasty and love how the food was packed to go. I ordered set #2 which also came with spicy shrimp which was also tasty, but a bit chewy. Might have been due to the drive home so can't knock it down too much until I try it again freshly made. Sauce was amazing though. It's similar to sweet and sour but with an extra kick. Order took about 10 mins but lots to do and see in H Mart while you wait. The biggest knock may be that I ended up spending $30 on other items while I waited :) read more

So I stopped by this spot while I was at H Mart for some dinner. The food took about 15 mins to prepare but I got to shop for groceries while I waited so that worked out. The food was fresh and the portion size was good. The Shrimp Fried Rice went well with Jjajang sauce, the sweet&sour pork was solid. I would go back in the future! read more

Newly opened inside H-mart, I saw that they had a jjajangmyeon and tangsuyuk combo ($25) which is black bean noodles with ground pork and chopped onions in a fried, salty fermented soybean paste with wheat noodles. Tangsuyuk is crispy sliced deep fried pork with a thick, sweet sauce on the side with cucumbers, pineapples, and onions in it. They served a pork version which was crispy with a not too thick batter. The menu consists mainly of Korean-Chinese fushion, they also got jjampong which is a spicy seafood noodle soup. The staff is nice and the wait time was not long. read more

I was super excited to eat some black bean noodle and sweet & sour pork. Their sauce for noodles, super super good! But the noodles were over cooked and mushy. Couldn't bring myself to finish it. Sweet & sour pork pretty good. Probably come back for the pork. read more

Great Korean-Chinese spot inside H Mart. The jjamppong had a rich, flavorful broth with plenty of seafood, and the tangsuyuk was perfectly crispy. Everything came out fast (about 10-15 minutes), which was a big plus. Good portions, great taste, and quick service -- definitely coming back! read more

Great tasting food here. The chajangmyun and sweet and sour pork was my favorite. Also, they have very friendly staffs especially the one works at the cash register . read more

A solid menu of everyday favorites. The ingredients tasted fresh, and the fried dishes were perfectly crispy. Both the Jjamppong (spicy seafood noodles) and fried rice were very generous in portion. Highly recommend if you're looking for a satisfying meal read more

3 STARS. We ordered the Gan Jjajang and Jjambbong Set No. 3, which comes with sweet and sour pork. However, the sweet and sour sauce was served cold--it's usually supposed to be warm. The Gan Jjajang was quite oily and lacked the expected savory balance, making it hard to finish. The Jjambbong was also greasy, with too much of the smoky "fire flavor" oil added. read more

The noodles were very good and the customer service was very helpful and patient with me. Recommended!

This restaurant is located in the food court of a grocery store. We came towards the end of the night so seating was ample. It was hard to choose because everything looked appetizing, but I ordered number 6, the spicy beef soup, and chose noodles instead of rice because the noodles are hand made. It takes about 15 minutes to prepare but it was worth the wait because it was delicious. It arrived in a large bowl with 2 big beef bones. The meat was juicy and the marrow was savory. The soup was hearty and the noodles were thick and had perfect bite. It came with a side of kimchi and radish and cilantro for garnish. The spicy paste was placed on the side so you could add it to your desire, but I have to say that the soup and the beef was already very flavorful without it. The portion size is perfect for the price and you could even share this with another person if you wanted, though I finished it all on my own because I'm simply voracious. I saw a lot of people coming by to pick up to go orders so this seems like a popular place with repeat customers. I'll definitely return soon to try the other dishes. read more

Red Dragon - #6 Spicy beef soup with noodles - Noodles Near Me - Diamond Bar, California

This is the second time I've tried this place. First time it was very good. There was a good amount of ingredients inside the soup. This time unfortunately is a miss. It tasted like a vegetarian soup. There was literally 2 pieces of squid and a tiny piece of meat, and a normal amount of vegetables. Very inconsistent. read more

I've tried so many restaurants' Jajangmyeon in the past, and I can honestly say Red Dragon has one of the best tasting Jajangmyeon out there. Also, their sweet & sour pork was very good as well! One thing that I agree with a recent reviewer is that the noodles may be just a little mushy or over cooked. But that's just me, others may like it like that. I've yet to try their Gan Jajangmyeon. Wish there's a Gan Jajangmyeon/S&S pork combo. Anyway, I'll definitely be coming back for more! read more

The food here is amazing. Me and my Dad come back all the time. The Jja Jang Myeon and the Jjam Ppong are two of our personal favorites. The staff are so kind and generous and the service is fairly fast. Would highly recommend! read more

Food was reallt good!!!!! Jjajangmyun and Tangsuyuk was so delish!!!! I want to go back for other dishes!!!

The staff were very kind and made my visit worthwhile. It is very convenient for me. Loved it! Will recommend with five stars. It almost tastes like homemade food. Food quality and price are fair. Sweet-sour pork is still my favorite with spicy seafood noodles :) read more

This is the place you should go if you are JJam BBong lover. JJam Bbong is exceptionally good compared to other famous franchise JJamg BBong restaurants that I used to go to. It was spicy, but I like spicy so it was good too, but they said they will adjust the spiciness if you ask to make it a little less spicy. By the way, I recommend a little less spicy, even though I will keep spicy JJam BBong. GREAT PLACE !! read more

came to eat before they opened (not realizing they were closed) and they made sure to still take our order. Food was prepared quick and was tasty! They even surprised us with a sprite on the house. Super friendly customer service would recommend to anyone. read more

We stopped here on a slow Saturday evening. Ordered jjampong and unfortunately waited over half an hour for our food. No apology for the long wait, and we noticed it took a while for other customers to receive their orders as well. Jjampong itself was above average in taste, would rate it 7 out of 10. read more

I had the absolute pleasure of eating Jjam ppong and tang soo yook (sweet and sour pork) at Red Dragon today! It's a nice addition to the food court at Hmart in Diamond Bar. The broth of Jjamppong was rich and flavorful, with just the right amount of spice. It was packed with an array of fresh seafood, good noodles, and veggies. As a Korean, I can say their sauce for tang soo yook was not too sweet, not too sour, just a perfect balance. The crispy pork pieces were crunchy on the outside, and juicy and tender on the inside. They went really well with the sweet and sour sauce. I'll definitely come back here to try Jja jang myun next time. I highly recommend checking out this spot if you are craving Jjam ppong and Tang soo yook! read more

A solid Korean noodle joint located inside Diamond Bar Hmart. The dishes are tasty and affordable. Highly recommend!
