14 Best Korean Restaurants in Diamond Bar

“I ordered from for the first time today and I must say that it was the greatest decision I made today! I ordered their Katsu sandwich and fries and it was delicious!

The bread was soft, the Katsu was crispy and full of flavor and most of all the coleslaw on the middle was sweet and tasty! The fries were the perfect side to it, they were cooked just right and they complimented the sandwich so well.

They also have a variety of drinks that can cater to everyone's tastes. Even though it ordered a coke today next time I will try the tea.

Hungry Bulldog House you have got yourself another customer that will be returning hungry for more on a different day!“

“This is a soondubu (spicy silky soft tofu soup) restaurant like BCD chain. You can order combo menu with a meat or fish entree with a version of soondubu soup. You can select the spicy level and toppings for the soup. I thought the soup is really good but the meat dishes except for the LA rib were too sweet. Ban Chan (side dishes) were just average. For Diamond Bar I think this outlet is fine. There is plenty of parking in the shopping mall lot.

Parking: Plenty

Wheelchair accessibility: It’s on the ground floor with wheelchair ramp.“

“This side dish shop is the best I've ever been to. It tastes more Korean than Korea, and the quality of the kimbap in particular is sky-high. Keto kimbap without rice is new and healthy. This place has become a place I must visit every time I pass by.“

“delicious food. good selection of meats. short wait for a table. our server Ethan was great as well as all the other staff.“

“My family and I are loyal regulars at Young Dong Tofu House—it’s hands down our favorite among all the tofu houses we’ve tried!

The restaurant is always clean, and comfortable, and the service is consistently excellent. The staff are attentive and often check in to see if we’d like more side dishes, which we truly appreciate.

Among the side dishes— the kimchi, bean sprouts, and fish cake are my top favorites—fresh, flavorful, and always satisfying. The tofu soup paired with brown rice is simply perfect. And the best part? The rice that gets crispy at the bottom of the hot stone pot can be softened with roasted barley tea to make a comforting scorched rice soup—it’s such a delightful way to end the meal.

Every visit leaves us full and happy. It’s not just a meal—it feels like comfort in a bowl. Can’t wait for our next visit!“

“Second time eating here when I stop by the super H Mart. Food always comes out fresh and tasty. Only positive things to say about this establishment. Steam buns and dumplings are my go to choice. Definitely be back again to try other dishes.“

“Best duck in the Diamond Bar, Rowland Heights, Chino Hills area. We always order duck served 3 ways - soup, sliced peking duck with thin wrap and green onions, and deep fried duck bones. While you’re there get some of the crispy pork belly too .“

“We had Gamjatang and the seafood pancake, and the pancake was so good with a lot of actual seafood, and the gamjatang soup was just amazing! The flavor of the soup didn't feel artificial or sharp, and instead had a very deep but smooth flavor that I appreciated a ton. Me and my wife easily finished the meat in the gamjatang, and brought the soup back home to make fried rice and that also tasted amazing! Will be back again for more“

“Went on a lunch date with my cousin. Thanksgiving left overs weren’t enough for us lol!

Parking: They’re located in the corner of a plaza. Free parking lot. We couldn’t find a spot within their area, so we parked near the grocery store.

Ambiance/Environment: They have a very casual, warm, & welcoming environment. They also have a small space. There’s a decent amount of seating.

Service: Once you walk in, you’ll be greeted and asked whether you’d like to dine in, take out or pick up. We decided to dine in. Shout out to Jesse & James! They were very knowledgeable about the menu, courteous, and attentive! We ordered via the tablet and paid at the register in the end.

What we ordered:

1) Combo B - We decided to share the Yupdduk (jjajang spice level). This came with boiled eggs and veggie fries and sweated rice balls on the side. The veggie fries had the perfect crisp, the rice balls tasted as expected, and the boiled eggs were cooked well. The sauce was absolutely flavorful! The rice cakes were very fulfilling! Make sure to immediately mix the cheese!

2) Boneless Chicken Feet (appetizer) - We were told this was one of their popular appetizer. We ordered this mild. Their special sauce was also flavorful! The chicken feet were cooked well. Although I’m not sure what makes this boneless bc I bit into small pieces of bone .. lol.

3) Spam Mayo Rice Bowl (appetizer) - Another popular appetizer recommended to us. We really enjoyed this! Can’t go wrong with a classic dish!

4) Fish Cake Soup - My cousin wanted something soupy. The soup wasn’t too salty. It came with a generous amount of fish cakes. Perfect for the cold weather.

5) Salted Caramel Milk Tea w/ boba (100% sweet) & Mango Green Tea w/ Lychee jelly (0% sweet) - I really enjoyed my drink! The boba was okay .. some pieces were chewy and some were hard. We were told the Mango Green Tea already has syrup, so she didn’t want anymore sugar. It was still a bit sweeter than she’d like, but she did enjoy the lychee jelly!

Pricing: The prices are fair $$, especially for the amount that you get. Everything was so flavorful, rich, and fulfilling.“

“Shhh…hidden gem! This ayce kbbq restaurant is outstanding! I’ve been to many kbbq places over the years and Seoul BBQ is top notch. Everything came out quickly, including the fried potstickers, water refills, meat refills, and grill changes. It was a laid back atmosphere, not a bunch of announcements or loud music. It had a good vibe for talking and hanging out with friends. We enjoyed several rounds of meats from the A and B menus, multiple grill changes, some peach flavored rice wine, and a fun time with friends and family. The beef bulgogi and beef brisket were excellent; everyone else in the group also enjoyed several other cuts of meat including garlic pork belly, flying tiger beef, short rib, beef belly, and others. The parking lot was a bit rough so beware. Everyone that went into the restaurant seemed well dressed and happy to be there.

Parking: There is currently some barricaded construction which has blocked some of the parking spots (Dec 2024), making it difficult to find parking. There was also broken glass in one of the stalls which raised concern about cars being broken into recently. Turn on your car’s camera if you’ve got one.“

“Pleasant surprise for a great meal after golfing across the street at Diamond Bar. Meat was fresh. Bangchan was tasty and service was good, granted that it was a quiet night. The decor was kind of odd for a BBQ spot but the price performance is great.“

“MY FAVORITE KIMBAP PLACE SOOOO FAR! Since we've tried it, we always look forward for Sundays and having them for lunch. The beef kimbap is soooo great that I'll say it's the best tasting kimbap I've ever had. The portions are great for the price too! This place won't disappoint.“
