A Legendary Slurp - Gone But Never Forgotten It is a true…read moretragedy for the Orange County food scene that Hakata Ikkousha in Costa Mesa has closed its doors. This wasn't just a "ramen joint"--it was a masterclass in authentic Fukuoka-style soul food. The Broth: Liquid Gold The standout was always their Signature Tonkotsu broth. You could literally taste the 30+ hours of labor that went into it. It had that distinct "frothy" texture (the bubble of the bone marrow) that you only find in high-end Hakata shops. It was rich, creamy, and carried a deep umami funk without ever being overly greasy. The Hits * Black Tonkotsu: The roasted garlic oil (mayu) added a smoky, dark complexity that ruined all other garlic ramens for me. * God Fire: For those who like to sweat, this offered the perfect balance of heat without sacrificing the integrity of the pork flavor. * The Karaage: Genuinely some of the best fried chicken in the area. Massive, juicy thigh meat with a shattering, thin crust and that addictive spicy mayo on the side. * Customization: I loved that they let you pick your noodle firmness. "Hard" was the only way to go to ensure that perfect snap with every bite. The Atmosphere The Costa Mesa location always had a great energy--functional, clean, and unpretentious. The staff were always efficient, greeting everyone with a loud "Irasshaimase!" that made the experience feel truly authentic. It's heartbreaking to see such a high-caliber spot leave the neighborhood. If you were lucky enough to eat here, you know we lost a heavy hitter. To the team at Ikkousha: thank you for the memories and the best bowls in the city. You'll be sorely missed! Note: For those still craving that specific broth, their Torrance locations are still holding it down--definitely worth the drive to keep the dream alive. Come back to OC! !

It's a little tight inside too with the tables located near each other. We came on a Monday during the lunch hour. We originally had plans to eat somewhere else, but it was too long of a wait and we decided to have Ramen instead. I think due to our party of six, it was a little harder to be seated, but it wasn't a big deal. We checked in and we were informed by Justin that it wouldn't take too long for our table to be ready as the other family who was at the larger table was already eating their food. Great! We meandered around in the center and walked inside Daiso and Mitsuwa market and already thinking about where we would be eating next time. We received a text when our table was ready about 30 minutes later. The nice lady who took our order was friendly, sweet, smiling and made us feel welcomed. We all ended up ordering different Ramen bowls, and curry with rice. We also shared the large fried chicken and furikake french fries. I'll have to try that at home next time! Everyone enjoyed their choices. I tried the light Kitakata ramen this time because I usually always get miso or Tonkotsu. The light broth was easier for me to handle and I was able to adjust the spice level with condiments on the table. I also used some of the chili spices from my family members. As usual, the chewy bouncy noodles were enjoyed by everyone. We will be back!

And she was smiling when I had to switching. Very evil woman. ( she has an acne patch on her face with star shape ) She has so much attitude for no reasons and clearly she doesn't have kids so she doesn't understand safety issues. 2. My husband ordered Charshu without green onion and came with a tons of green onion. That's strike 2. 3. I asked for a check and she ignored us for 10 mins and I had to ask someone else. We ended paying in a front like a fast food service. I will talk to the manager next time about her and I hope she gets fired because I talked to my neighbors and they said the same thing. It's really sad because they have really good food but the service ( specifically her) is terrible and it soured our mood. People come to the restaurant to enjoy the food but she has such a bad attitude because she is not happy in her life.

I considered tonkatsu ramen but decided to order a large spicy miso ramen instead, Make it a large for $1.50 is a great deal. I found myself staring at a mount of vegetable toppings when my ramen arrived. The next thing I noticed was the wavy kitakata noodle that reminded me of chewy homemade noodle. I tasted the broth by itself before slurping in my ramen. The whole package was a winner for my taste buds. I learned from Madison that this location in Costa Mesa was established in 2014, the first international Kitakata joint outside Japan. Although this is my first time at Kitakata certainly won't be the last.

Their original Hakata ramen feels like it's not as consistent as some of their other branches. The restaurant has nice high ceilings and a variety of different table sizes. The lines here are much shorter compared with other locations and you can typically get a table without a wait unless you go at peak hours. There are frequently new menu options or seasonal specials that are worth trying out. On the last visit, tried the new sushi tacos. The sweet shrimp was very good, but I wouldn't recommend the beef.
