Kopan Sushi & Ramen Reviews

Delicious sushi with an extensive menu in the heart of Downtown Fullerton! The ambience was creative and casual. Right in the middle of all the shops and bars. The food was flavorful and the prices were fair, they had some good deals like buy a roll get one half off, buy one hot sake and get a second for .99cents. Its a lowkey local spot but feels like you’re somewhere in Japan. So much to choose from menu wise, cold food, hot food…Yumminess for days!
May 18 · Knicole
This spot in Fullerton is super close to CSUF, and honestly feels like a second cafeteria for students. The prices are super budget-friendly, the menu has a ton of options, and the flavor is consistently good. The vibe is very much like a retro-style Japanese izakaya.Came here with some friends and ordered a table full of shareable dishes—everything was solid:Bento BoxYou can choose two or three mains—I got takoyaki, Korean beef, and teriyaki chicken. It comes with rice, miso soup, and salad. Generous portions! The chicken was tender and flavorful, beef on the sweeter side but not too much, and the takoyaki had bonito flakes which added a great touch.Negitoro Rice Bowl + UniThis was super Japanese in style. The toro was finely chopped and creamy, mixed with green onions and uni. Best eaten wrapped in nori—rich, fresh, and melt-in-your-mouth.Tokyo RollSpicy tuna and cucumber inside, topped with spicy albacore, avocado, and crispy onions. The sauce is a mix of spicy yuzu ponzu, eel sauce, and spicy mayo. Flavor-packed but well-balanced.Baked Scallop California RollA classic California roll base topped with baked scallops, slightly charred, with mentaiko sauce and eel sauce. Hot, savory, and comforting.Grilled King Crab BitesCrunchy base with a heap of crab meat on top—clean flavor and great for sharing.Salmon TartareFinely chopped salmon mixed with sauce, served with crackers. Refreshing and a nice appetizer.Spicy Lemon Grilled OctopusCrispy skin, super tender octopus, and a tangy spicy sauce that really stands out.

Recently, I’ve been loving this hidden gem of a restaurant! I really enjoy the cozy Japanese ambiance—it’s very comfortable. The staff is incredibly friendly and gave us great recommendations that turned out to be delightful surprises. I especially love the tonkotsu ramen; the broth is rich and flavorful, and even the kids enjoyed it. We also ordered the Ginza sushi—the sashimi was incredibly fresh, and the presentation was beautifully done. This is definitely a place I’ll keep coming back to!

Taste :4.5/5Environment: 4.5/5Service：4.5/5Even though it’s called a ramen shop, Kopan Sushi & Ramen honestly feels more like a cozy Japanese izakaya that's been hiding in plain sight. The whole place has serious izakaya vibes — warm lighting, casual energy, and the kind of menu that makes you want to hang out all night.Bonus points: they even have a “buy a bottle, get one free” deal, which feels like a love letter to all the hardworking people who just need a drink (or two) after a long day.Some recommendations💛Sesame Chicken – crispy, savory, and ridiculously addictive.💛 King Crab Bites💛 Chili Lime Tako – tender octopus with just the right kick.💛 Yuzu Miso Black Snapper Crudobright, refreshing, and full of flavor.💛 toro Donburi fresh salmon over rice with a citrusy pop.💛 Hotate Crudo – Scallop with Caviar– rich, delicate, and basically impossible to resist.💛Ginza sushi platter is the showstopper here — colorful, eye-catching
April 30 · Paprika Meow
This Japanese Restaurant Is Absolutely Amazing!Recently, my friends and I visited an incredible Japanese restaurant, and the entire feast was beyond satisfying! As soon as the food arrived, it was a visual delight. The beautifully arranged sushi platter in a wooden box was a true work of art—each piece was a bite of happiness. From uni to salmon and botan shrimp, every bite was incredibly fresh, perfectly paired with wasabi and soy sauce for a burst of umami flavor.Beyond the sushi, the sashimi was another highlight. The yellow citrus dressing added a refreshing touch to the raw fish, complemented by microgreens and gold flakes, making it as stunning as it was delicious! The ramen options were equally impressive—crispy tonkatsu ramen with a rich broth and a spicy ramen with a mildly spicy soup base, topped with an onsen egg that added a comforting warmth to every bite.Of course, we couldn’t skip the Japanese side dishes and seafood rice bowls. The thick-cut sashimi covered the entire bowl, packed with the freshest ocean flavors. One unexpected favorite was the chilled cucumber and avocado salad—such a delightful surprise!Every dish was truly outstanding, and the cozy ambiance made it a perfect spot for gatherings or dates. Highly recommend this place to all Japanese food lovers—definitely a must-visit!
