Restaurant is on the first floor towards the back and is super chic inside. Restaurant itself is not very big, so you may encounter a wait.. but it's worth it. Plus the staff is friendly - they tell you up front about the included 17% gratuity. Ramen is perfection. Egg noodles are the perfect texture and the tonkotsu broth is so good! I added a heap of garlic as that's my preference, but you can get garlic on the side. The chashu top is nice and juicy as well. All in all a solid spot.

The broth was rich and flavorful, and it really hit the spot. Everything tasted fresh and well prepared. The service was exceptional, and the staff was friendly and attentive throughout the meal.

The dipping ramen here hit the spot. It was super flavorful and I got the spicy option and enjoyed it because the spicy enhanced the flavor without making me get spiced out. The noodles were perfectly al dente and the broth was so so good. Meat on top was also very tender. I got the karaage as an appetizer and it was very juicy and bursting with flavor. The host was very attentive and gave us the right amount of check-ins while filling our waters. I liked the chill atmosphere and it was nice and cold which I need because the summers here are so hot. Definitely coming back again!

I didn't feel like going all the way…read moreto LA for ramen at my usual spot, so I looked up some places around me and discovered Butaton which I've ridden past multiple times. I ordered the Butaton ramen which had everything I like! Minus the bean sprouts. Pretty good bowl of ramen. The noodles were PERFECTLY al dente. The broth was good, but maybe a tiny bit too salty. You could definitely feel/taste the collagen in the broth which was nice. The pork belly was a bit tough and dry though. Portion wise it's pretty small. At first I was considering doing the lunch special where you can add a beef or chashu bowl for an additional $6, but I thought, "Nah, that's going to be too much food." I guess in the end it worked out. I was the perfect level of full/satisfied. However, if you're starving I would definitely recommend doing the lunch special. It's a nice space to dine at for sure! I enjoyed watching the cars/people flow through the Orange Circle while I was eating. Service was fast/friendly. No complaints there. A little steep on the price versus portion though. This meal was almost $24 after tip for a bowl for ramen. Overall, not bad! I've had much better elsewhere, but out of all the local spots I've tried around me so far, this one is definitely one of the better ones so far.

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! !

Attentive staff and really great food!…read more Let me start by saying this has officially become my new local go-to ramen spot. I've tried plenty of hole-in-the-wall ramen places, and while many are good, a bowl can sometimes feel overpriced. This place gets everything right. I ordered the Habanero Ramen, and my fiancée had the Signature Black Pork Ramen--both were excellent. We also noticed they offer a combo deal, which made the value even better. With the quality of the ramen and everything included in the combo, it honestly feels almost too good to be true. Great food, great value, and friendly service. I really hope this hidden gem sticks around for a long time because you'll definitely be seeing us here often!

Our server wasn't very personable but also not rude or terrible. I felt a little rushed even with a small menu. Being that I had never been there before, I wasn't sure what to get so I pretty much just blurted out whatever. What we ordered: 1) Black deluxe chicken paitan with pork - the broth was so tasty, it was absolutely delicious. The pork slices were generous, however, it was DRY. 2) Pork chashu - for my kid. They loved the broth as well and also felt that the pork slices were dry. I wanted to give 4 out of 5 stars, but I am going to hand them a 3. I loved the tasty broth, but the pork was too dry. How could you mess that up as a ramen restaurant? The portions looked a little smaller than what I am used to paying for much less money. That photo of my black deluxe chicken paitan with pork is very deceiving. It looks like a lot, but it definitely wasn't. I usually can't finish my bowl of ramen in one sitting and take the other half home. I barely had any broth in there, and being that the broth was very good, I was disappointed to run out of it before I was even done with the noodles and meat. Would I return? Sure. I liked the food. It's not a place I would go out of my way to eat at, but if I was around the neighborhood and wanted ramen, I would dine there again.
