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!“

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

“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.“

“This is the place we went to have a quick bite when we moved to Diamond Bar 8 years ago and then we found so many other places to eat and almost forgot this restaurant. Recently we visited this place again, the menu is same except price a little higher. The quality of food are same but now they gave you disposable chopsticks instead of re-usable ones in the past. Other than that, not much change, always busy but the waiting time is tolerable. I like this beef BBQ rib combo with seafood tofu soup and they are good. They don’t have steak knife but so provide a pair of scissors and a small pair of tongs so that you don’t have to eat BBQ beef with just chopsticks.“

“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.“

“ATOYUBU Diamond Bar is my new favorite spot! The yubu pockets are fresh, flavorful, and beautifully made every bite tastes amazing. The spicy tuna and bulgogi were standouts, and the presentation is top-notch. Staff are friendly, the space is clean and modern, and everything feels high quality. Perfect for a quick meal or takeout. Highly recommend!“

“I genuinely want to say I like their duck because I really do. But if you plan to order takeout, I recommend getting a half duck or whole duck rather than the bento.

The first time I visited, I came with friends and we ordered a whole duck. It was excellent. That’s why I returned this time to try their bentos. I ordered a roasted duck bento and a salted duck bento. Unfortunately, both bentos were mostly filled with duck neck, and the salted duck bento even included the duck head, which was quite shocking when I first opened it. None of us eat duck head in our family, and it would’ve been nice if they at least asked, since it’s definitely not to everyone’s liking. There wasn’t much actual duck meat aside from a few pieces in the bento boxes, which was disappointing.

As I said, I really do enjoy their duck, the roasted duck was delicious. But the cuts they used for the bentos were not satisfying. I wouldn’t order the bentos again, but I would definitely come back for the whole roasted duck.“

“✨Who knew that seaweed rice balls would be the star of the meal?✨ You can expect every table to order that @yupddukdiamondbar amongst the many incredibly comforting dishes here🫶🏼

“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.“

“Seoul BBQ is a solid spot if you’re craving AYCE Korean BBQ 🔥
Great quality meats, quick refills, and that fun grill-at-your-table vibe that never gets old. Perfect for group hangs, meat lovers, and anyone who wants to eat a lot without stressing the bill.
Why it’s worth it:
🥩 All-you-can-eat meats (beef, pork, chicken)
🔥 Grill at your table = always hot & fresh
🥬 Banchan + sauces to mix & match“

“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“

“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.“
