I've been…read moreto the Irvine and Torrence location as well and all locations are on par and produce the same quality ramen. 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.

Although this place is a little hidden, it's definitely worth finding. I didn't realize HiroNori…read morehad multiple locations, but I was invited here for lunch and decided to try the Shoyu Ramen. 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. It's a smaller space, but I visited during lunchtime on a Thursday and it wasn't busy at all, which made for a relaxing experience. Overall, a great little spot and one I would gladly visit 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.

We got an order of hot sake, spicy miso ramen, and hanuman ramen. Spicy Miso Ramen- You get chashu, soft boiled egg, bamboo shoots, bean sprouts, and green onions. The meat is tender, broth has a good amount of spice, and the egg and veggies make it hearty. Butaton Ramen- The chashu practically melts at the mouth. The broth is creamy and savory. You get egg, woodear mushrooms, bean sprouts, and green onions add a variety of textures and flavors. House Sake Warm- At 7$ a bottle, this was a steal! It's smooth and hits the spot on a cold day. Great experience overall!

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! !

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!
