15 Best Korean Restaurants in Diamond Bar

“I really need yall to know I don’t do reviews unless something actually moves my soul. This is by far, the BEST katsu sando I’ve ever had. I finished and sat in my car and just contemplated life, completely forgetting the taro ice cream I had bought. I wish I could eat this again for the first time. 15/10 food, the service was amazing and prompt. Come on an empty stomach.“

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

“First tried this chain in Buena Park and was so excited to see them open in my home town! Literally searched for similar options in SGV but closest seemed to be Kingyubu in ktown that I didn’t like as much. Now this is a go to when I visit the parents. Have always loved inari as a guilty pleasure (so basic, I know..) and this concept takes them to the next level. Spicy options have a good kick and the toppings are plentiful. Im usually passing so I order online via toast and pickup no problem.. but then I can’t even make it out of the parking lot before I give in and gobble them up. Popping spicy salmon and garlic butter crab are my go tos.“

“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 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 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.“

“Great taste of duck dishes with both Northern Chinese and Southern Chinese style roast ducks. Awesome value for its lunch special bento, considerable portion of duck and side dishes, and competitive price. The only limitation is the restaurant is closed on Tuesday so that it is not convenient enough for me as I need to go to office nearby on Tuesday but cannot have food at that days.“

“✨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🫶🏼

First time trying Korean comfort food or don’t know what to get? Order this lineup and thank me later:

🥚Omelette Rice
🐷Pork Cutlet
🍗Chicken feet
🍙Seaweed Rice ball
🍲Beef bulgogi stew“

“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“

“The buns here are stuff to the brim with filling with chives, glass noodles, wood ear mushrooms, and pork. Its a great quick meal to have after a long day because of how large the bun is. The frozen dumplings from here are also very generous in filling and are best boiled as soup or pan fried. The taste is meaty.“

“Spending time with Mr. Oh of Diamond Bageloo, who puts philosophy and soul into every bagel he makes.
For dinner, we went for the locally famous sundae soup. Wow—no off-flavors at all, just a hearty bowl filled with assorted sundae, perfectly arranged in the pot, accompanied by crisp, refreshing radish kimchi.
Seeing the walls adorned with celebrity-signed frames, it’s clear this place isn’t just any ordinary spot—you can truly feel its quality after tasting it firsthand.“

“The food portion is large, even though each dish is $15+, but with the side dishes, soup, and rice they give you can definitely split it into two portions. The bimbibap wasnt too salty and the texture of the veggies were fresh. The broth is just beef broth...a little salty but its a nice hot side.“

“First time here around 4:30pm on Sunday. It was really amazing and the quality is greater than all you can eat. We ordered a combo $79, and the staff was very nice and we learned a little bit Korean from her! Thank you so much for your service and we highly recommend!“

“Those little food stalls inside H Mart are the best, especially when there’s an older lady who’s been there forever—always kind, warm, and makes the food taste even better. That fish cake soup hits different, especially on a cold day. Simple, salty, comforting…total Korean soul food.“
