    Tteokbokki
    Michelle K.

    I was in Buena Park for a hair appointment and was recommended this place, so I ended up ordering to-go: one pork katsu and tteokbokki combo along with two pork katsu sets. It's pretty difficult to impress my parents with outside Korean food, but even they were surprised with the quality and quantity of food provided. They were especially in love with the tteokboki, which was not too sweet and had great rice cake texture. The katsu was pretty typical but I loved the corn potage (or potato?) they provided on the side. I definitely want to come back and have this again the next time I'm in the Buena Park area!!

    I usually get take out from here and love their chicken curry katsu. My usual order used to be just the chicken katsu but the curry adds on an additional level. Their kimchi radish side dish is also really good. I usually skip the white soup they provide (it tastes kind of like powder to me).

    Banchan and sauce
    Mary Ann C.

    I highly recommend Joon Katsu. Absolutely delicious katsu options at very reasonable prices. Excellent staff. Interior is a bit tight when it gets busy but the staff is very efficient. Portions are definitely on the generous side so come hungry. Delicious side dishes too. Shares the parking with Zion supermarket plaza so parking was a breeze as well. Afterwards, you can check out a dessert spot nearby and get some grocery shopping done too! So many other great spots to check out in this area after stopping by for a satisfying and nourishing meal at Joon!

    Donkatsu
    Jeremy S.

    I went here wanting to try another donkatsu restaurant in Buena Park. I ordered the donkatsu and soba combination. The combination adds the option of ordering either soba or udon. The portions are large, so I'd recommend coming here especially hungry. Aside from complementary banchan and a creamy soup, we also ordered steamed dumplings and crispy shumai as appetizers. These were all decent, and the steamed dumplings' filling included meat and japchae. The donkatsu, cut into thick yet tender slices, tasted delicious. Its portion was just right and came with a sweet and tangy dipping sauce. The dish also came with a shredded cabbage salad with a bottle of Japanese-style dressing already placed on our table. I wish that it came with more rice, though. It was my first time eating soba noodles, and I enjoyed it. There was a dipping sauce that tasted like a lighter and sweeter variant of soy sauce. From reading more about this sauce online, I believe this was mentsuyu. There was also a small bowl of relishes, including wasabi, grated daikon, and chopped scallions. By itself, the soba had a nutty flavor. I decided to pour the sauce and relishes into the soba, which made it refreshing with a delicious blend of savory and sweet flavors. Service was good, and the staff was really nice. The restaurant wasn't busy when we ate here. The ambience was relaxed and casual. One point of improvement would be providing a water pitcher.

    Pork Katsu and Spicy Rice Cake
    Brigitte L.

    Recently opened is Joon Katsu and their Katsu was life changing (seriously!) I ordered the Spicy Rice Cake + Tonkatsu Combination and that along can feed two. The Katsu was perfectly fried, super crispy, yet retaining the juicy and tender interior. I really enjoyed the sides of curry they provided to dip the Katsu into. Between the spicy mayo sauce and curry, I preferred the curry :) We didn't even get to really dig into the rice cake because the portions were just HUGE! The rice cakes were pretty spicy and savory, the rice cakes nice and chewy. HOWEVER, the standout was most definitely the sweet potato Katsu. Ive never had the sweet potato spread across the top of the Katsu, but the blend of umami pork and sweet potato was perfection 12/10. The inside of the store is very humble and feels like ones home. I can't wait to go back and have that sweet potato Katsu because it is THAT good.

    Everything was perfect. I was headed to Yoko but they didn't open yet so I decided to try this new jem. Honestly, I would say it was a bit better then yoko for me. Much more fast to get the foods but still foods are amazing. The server was nice too. The one thing I wanted was the baby diaper change pad on restroom. Definitely I'm going back to this place!!

    Katsu and Udon combo
    Justin S.

    I was looking for food cause i met up with a client and stopped by here glad I did! Ladies working here was super nice and attentive place was clean. Ordered the udon and donkatsu combo everything was super good no complaints def check it out.

    Amazing food! It's a small gem in a plaza that cranks out many orders. For good reason. The menu is simple, and it's good. I ordered the pork and chicken katsu And cold noodles. The banchan were flavorful. Service is fast. So is the ambiance. Worthy of being in the rotation

    Chicken Katsu
    Nadeem K.

    Drove a couple miles to Buena Park on a whim for lunch. Was craving some variant of fried chicken and found this establishment right next to Zion supermarket. Parking is quite abundant since Joon Katsu shares the same parking lot as the grocery store, so no problems there. It's a smaller shop so the interior is a bit cramped with less seating (although very clean) as it gets moderately busy during lunch hours, but that's what adds to the charm I'd say. The staff was amazing; got me seated right away with some banchan to stave off my hunger. Even better, they got my order out in under 10 minutes. Super efficient service definitely brightened my mood a good bit! The banchan included some cucumber kimchi, radish cubes, jalapeno slices, bean sprouts, and some soup (not too sure what type it was but I enjoyed it). I honestly wasn't expecting any banchan to come out to begin with, so I was just happy to have something to snack on. Not much to say except the vegetables had a great crisp, so I was more than satisfied. Again, props to the staff for getting that out so quickly. I decided to order the classic chicken katsu, which came with some warm katsu sauce, a cabbage salad, and a scoop of white rice. The katsu breading was perfectly crisp, even with the sauce poured over it. Of course, the meat was sufficiently moist. Keeping the sauce warm was a great idea so the chicken didn't get cold so quickly. The salad was fine, nothing to write home about but it tasted fresh. My only note would be that I would have preferred a larger standard portion of rice, but that is variably subjective for most people anyways. Pricewise, it came to around 20ish dollars including tax. Given the quality service and the size of the katsu, I think it was well justified. If you live around the area, I definitely recommend checking it out.

    50/5 stars!! Get the sweet potato katsu for the ultimate indulgence/if you're a fan of sweet and salty! Radish kimchi is quite amazing here, a little sweeter and less tangy than other places, but so addictive. Just a little under $19 before tax and tip for a shareable dish if you split between two ppl Comes with cream soup, salad, rice No Amex accepted ========== How this place isn't swarming with customers is beyond me. I wasn't even craving katsu, this has been a bookmark for awhile. Better late than never lol Where do I start? Thick pork slab Crunchy panko Sweet potato cream/filling Topped with an abundance of broiled mozzarella?? Cheese Crunchy katsu with sweet, soft potato and gooey cheese, finished off with gently sweet, tomato-based donkatsu sauce. A small bite of cold salad with their creamy dressing and a tangyish selection of their banchan. Sososooooo goooOoOoood. Dawa who? lol It was definitely a moment where I sit in silence, slowly chewing and listening to their Korean ballads they have going on in the background and everything is right in the world. Cream soup was decent, a touch gritty but black pepper would have been perfect. Banchan Besides the radish, the seaweed is also really tasty and the cucumber was pretty decent as well. You'd think for a donkatsu place, banchan should be whatever - NOPE, not here! Rice was slightly chewy and sticky. I used it primarily for the banchan. Salad was cold and crisp and came with corn, tomatoes, purple + green cabbage. The dressing was less mayo-y than other places and leaned a little more tangy. Service was wonderful. I got checked on and I complimented the lady on her banchans and she even told me how to make her radish one lol I told her no, I want hers haha I had half a donut before this meal, ate about 1/3 this dish and was still full. They have a combo that comes with soba for $25 or so! But that's too much food for one person. Also have pizza donkatsu, curry, etc... I'll try and come back once a every two mint?? so I don't get a heart attack hahah

    First time here. Friendly staff and perfectly fried, crunchy katsu with good banchan. Most katsu places skimp on salad dressing, but here they give you a whole bottle so you can pour as much or little as you like.

    Spicy Pork Katsu
    Brock S.

    I've been wanting to try this place but wasn't sure. When we entered, there were three tables filled with used dishes and only one worker so I was a little bit nervous. However, she was very friendly and we ordered and then she cleaned up all the tables and suddenly, it felt like it was going to be a good experience. I ordered spicy pork Katsu and I really thought the Katsu was nice. It was crunchy on the exterior and moist on the interior and did not have a lot of fat or gristle or anything so I was very pleased with the Katsu. Plus, it was a pretty decent large size. However , the "spicy curry" was on the side and really tasted more of like a hot barbecue sauce kind of thing. I was pretty disappointed, but not because it didn't taste good but just because it wasn't what I was craving. However, my wife ordered a curry rice bowl and the curry was filled with vegetables and tasted very good. Overall very enjoyable. But not like what you'd find in a traditional Japanese curry or Katsu place

They offer valet parking at the entrance, along with additional parking around the corner. Since this place gets very busy, I'd recommend arriving early to avoid a long wait. This is a great spot for large groups and celebrations.

And their hands go inside everything. They grab the rinsed pitcher, scoop the tea water and serve it. Also mind you, the tea water is inside those huge trash cans. AND when they were transferring the ice (from again those trash bins) they would lift it to pour all the ice in to the tea water bin and you can see all the dirty drippings from the outside wheels drip inside the container.. @.@ No its not a one time thing with one employee...they all knew the drill and did it like routine. Me and my friends watched the whole thing while we were just trying to enjoy some drinks at the bar. It was so disgusting, my friends wanted to pay and leave quickly but NO theres no way im paying for the drink i only had a couple sips of and couldn't finish. So i told the manager, didnt pay and left. He was not shocked ... wonder why. And now im just telling all my close friends not to go here... digusting.

I love that you order off their kiosk which is conveniently located at the table already. The staff was quick to bring out the banchan. To start, we shared their leek pancake and pork blood sausage. For my lunch I went with their cold noodles since it was a cold day. The people I came with had some pork spare ribs, which came with rice and bone knee soup. And a bibimbap. The leek pancake was the best thing there. The pork blood sausage was more of rice noodles rolled up with pork blood flavored. I can't imagine it being much portion. Eveything else was bland which we all agreed to. For my cold noodles I added plenty of vinegar and mustard but it was not it. Still lacked flavor. Also it only had half a boiled egg and two verythin slices of beef. The pork was over cooked, dry, and lacked flavor. The bibimbap was also bland even with their red sauce.

Their lot was full and you can park next door but by the dental office but that was also full. We waited a little and eventually found parking. The restaurant is very casual, clean and spacious. This was just really meh to me.
