Kopan Sushi & Ramen

We came here after a long day at Disneyland — three girls, starving and looking for somewhere cozy to eat and chat 🍺. We first tried to get into OC Lau, but the line was insane, so we walked next door and found this Japanese izakaya with great ratings.

So glad we did! The place has a relaxed vibe, super friendly service, and a full photo menu (love that!). Every dish came out beautifully plated — and, honestly, everything tasted as good as it looked.

🍣 Negitoro Donburi
Absolutely loved this one. The rice bowl came topped with three pieces of fresh uni, paired with bluefin tuna belly and scallions. The fish and uni were sweet, rich, and super fresh, balanced by crispy seaweed. Every bite melted in my mouth — a must-try!

🐚 Uni Scallop / Uni Toro
If you’re a uni lover, this is heaven. The scallop + uni combo was my personal favorite — thick, buttery scallop with the creamy sweetness of uni. One of my friends had the uni + toro version and said the fatty tuna was amazing too.

🔥 Seared Sushi Bomb
A fun “five-flavor” sushi plate — salmon, tuna, snapper, halibut, and yellowtail. I love seared sushi in general, and this one was perfection. Each piece had a different sauce pairing that worked so well with the fish.

🍄 King Mushroom Steak / Sodduk (Sweet & Spicy Rice Cake Skewers)
The mushroom steak was unexpectedly good — juicy, smoky, and full of umami. I’m not a big fan of rice cakes, but if you are, the sweet & spicy sausage-rice cake skewers are worth trying too.

🍋 Lemon Highball
You can’t go to an izakaya and not order a drink! This Lemon Highball was one of the best I’ve had — super lemony, refreshing, and dangerously easy to drink. (Half a glass in and I was already turning red 😆)

The food looked exactly like the photos, which is rare these days. The three of us ended up chatting and eating for almost three hours, just enjoying the food and the vibe.

Highly recommend for a girls’ night, casual date, or post-Disney dinner. Great food, good drinks, no rush — just good times 🩵

Kopan has always been popular in LA, and I’m so glad to find the Garden Grove location is just as amazing—maybe even better!

The place has a cozy dark-wood interior and a chill vibe, perfect for date nights or small gatherings. The service was also super attentive.

Here’s what we tried and loved:
1. Uni Scallop – Fresh scallop topped with uni and caviar, incredibly sweet and ocean-fresh.
2. Kara Miso Ramen – Rich, slightly spicy miso broth with tender chashu and perfectly chewy noodles.
3. Truffle Salmon Carpaccio – Thinly sliced salmon with truffle oil, aromatic and buttery without being greasy.
4. Unagi Donburi – Served hot with perfectly grilled eel and a well-balanced sweet-savory sauce.
5. Dragon Roll – Eel and avocado combo that’s flavorful and satisfying.
6. Torikawa Gyoza – Crispy chicken-skin dumplings, crunchy outside and juicy inside—so good with their dipping sauce.

Everything was on point, but the Uni Scallop and Truffle Salmon Carpaccio really stood out. Definitely a spot I’d come back to for a relaxed dinner or a date night.

I had the Tonkotsu ramen and it was absolutely delicious. The broth was creamy and flavorful, and the noodles had great texture and were cooked perfectly. We wanted a fresh sushi option instead of fried, and our server Kenny recommended the protein roll. It was a great choice, light, fresh, and really hit the spot. The ambience was nice and cozy, making the whole experience even better. Kenny was fantastic, very friendly, attentive, and helpful throughout the meal. Excellent service and great food.

I’m guessing the name Kopan comes from a mix of Ko (Korean) + Pan (Japanese) .

Tried their $18.95 Lunch Special. Ramen itself was okay, broth was nice, but the tonkatsu was a bit tough. Surprisingly, the spicy tuna roll and Mushroom steak were the best part.

Cute waitress with the sweetest voice totally made my day.

Cozy vibe, but for this price, I’d rather grab ramen at Gomen in Stanton which has better flavor and only $7.99 for lunch special!

Every time I come to Garden Grove, I usually end up eating Vietnamese food. But actually, the Korean and Japanese food here is also really good 👍. This time I went to the long-standing spot Kopan Ramen & Izakaya, and it was truly impressive!

Their focus is ramen and izakaya dishes. And indeed, both menus turned out to be top-notch.

Ramen:
We ordered a very unique pork katsu ramen. The first bite of the katsu was such a pleasant surprise! Crispy, flavorful, and tender inside—I couldn’t believe this was just a ramen topping 😂.
The tonkotsu ramen itself was also excellent. The noodles are thin, like Shinsengumi-style ramen, with a rich broth. If you like thin noodles with a bold, flavorful soup, you’ll definitely enjoy this.

Izakaya menu:
Although I don’t drink, I really love creative izakaya-style small plates. This time we tried stuffed avocado and stuffed green peppers—both were amazing! The peppers were lightly fried, giving a tempura-like crunch, with creamy cream cheese inside: crispy yet creamy. Highly recommend!
We also ordered a toburi bowl for its gorgeous presentation: tuna + uni + fresh wasabi over rice. Beautiful and delicious.

All rolls are buy 1 get 1 at 50% off, and the portions are huge—each one can count as a full meal. The flavor is the typical “loaded rolls” style: lots of ingredients stacked together. Pretty good, but if you don’t eat much, maybe skip this.
Sashimi was just average—you can pass on it.

Summary: The ramen and izakaya dishes are excellent 👍—flavorful and even surprising! Rolls and sushi are decent but nothing special; I’d recommend saving your budget for the first two categories. At lunch they also have a ramen + izakaya side dish special, and you can add a small dish (normally $11) for just $5—such a great deal!

We visited Kopan Sushi & Ramen in Garden Grove and it truly feels like a hidden gem. The interior has a cozy Japanese vibe with unique decor, and if you sit at the sushi bar you can even watch the chefs prepare everything fresh, almost like a mini omakase. We tried the Ginza Sushi Set, which was beautifully presented with each piece having a different topping and flavor. The Tuna on Crunchy Spinach was another standout — smoky tuna paired with crispy spinach for a great balance. The oysters were very fresh with no metallic taste, complemented by a tangy sauce. We also had the Uni Bluefin Toro and the Mango Salmon Roll, both enjoyable, especially the refreshing combination of salmon and mango. The restaurant offers a nice selection of sake, with half-off refills after the first order, and there’s also a promotion on sushi rolls (buy one, get the second half off). On average, you can expect to spend about $50 per person if you include ramen or donburi, but if you mainly order sushi and sashimi like we did, it may be closer to $70. Overall, great food, fresh ingredients, and a lively late-night spot open until 11 pm on weekends.

I RARELY give 5 stars let alone in all 3 categories but this place absolutely deserves it... from the O Toro on the menu to the care and precision of their sushi craft... this place exceeds in all areas. The service is always far above average... everyone is happy, pleasant, and tentative. The atmosphere is almost a role play of old Kyoto. There is lots of wood, lanterns, etc. It almost feels like youre transported to Japan. The food has been among the highest quality the past 7 visits. The ramen is consistently delvious, rich broth, the chashu is top top perfectly prepared. I cannot say enough good things about this location of Kopan. Its truly above all others

I've always loved their Rowland Heights location, so when I was in the area, I had to check out the new Kopan Sushi & Ramen Bar in Garden Grove! The restaurant is easy to find, located in a plaza right off the main road--just look for the menu sign at the entrance!
Stepping inside feels like teleporting to Kyoto! The decor is bursting with Japanese charm: a large glowing moon in the center, playful dolls on the walls, and intricate lanterns, with every detail evoking memories of our family trip to Japan last summer. Couples can opt for a cozy, private booth for a romantic vibe, while those who enjoy watching the action can sit at the sushi bar, where skilled chefs craft fresh sushi right before your eyes--talk about peace of mind!
The menu is packed with options, and the drink selection is a real highlight. My husband ordered a refreshing Lemon Highball, which was fantastic! Even better, after your first drink, all subsequent drinks (any kind!) are half-price! With a wide variety of sake and cocktails, this is a dream spot for anyone who loves a good drink. Plus, they're open until 11 PM on Fridays and Saturdays, a rarity in the area, making it perfect for late-night gatherings with friends.
We ordered a sashimi platter and uni scallop(uni, fish roe, and scallops). everything was incredibly fresh, and the uni was delightfully sweet and satisfying! We also took advantage of their buy one, get the second half-price sushi roll deal and got two rolls. The Truffle Hunter Roll was bursting with fragrant black truffle flavor--highly recommend! The other was the rice-free EX Girlfriend Roll, perfect for low-carb diets but still packed with flavor. We left full and happy, with the service being as warm and attentive as ever.
* Immersive Japanese atmosphere with impeccable details.
* Fresh, high-quality sushi and creative rolls at a great value with the promo deal.
* Extensive drink menu, with sake pairing perfectly with sushi and half-price drinks after the first.
* Open late until 11 PM on Fridays and Saturdays, ideal for nightlife.
* Perfect for date nights, casual hangouts, or sushi enthusiasts.
‍ Can't wait to come back! Highly recommend visiting Kopan Sushi & Ramen Bar for a delicious and authentic Japanese dining experience!

Stopped by Kopan Sushi & Ramen after visiting the Crystal Cathedral — it was so hot, I went for the Yuzu Miso Black Snapper Crudo and Japanese cold noodles, super refreshing. I always get sweet shrimp and uni sushi, and this time tried the chef’s recommendation, the Ginza sushi platter — fresh and looks great. The Unagi Donburi (eel rice bowl) was amazing too, tender eel with avocado and fish roe, really tasty.

They also have a deal where the second sushi roll is half off, which is pretty awesome. The place is open late on weekends, perfect for a chill late-night bite. Definitely coming back!

Just finished a heavy workout and came straight here without even changing. Absolutely hit the spot! The tonkotsu ramen was rich and comforting, the crispy rice with spicy tuna was super flavorful, and their hot stone beef sizzled beautifully. I brought my mom who doesn’t eat raw fish, and she loved the veggie ramen and grilled items. The vibe here is cozy and very Japanese izakaya-style. Perfect for dinner or late-night cravings. Definitely coming back!

After exhausting most of the food spots in Irvine, I recently stumbled upon this cozy little tavern in Garden Grove — and wow, it’s a game-changer. At this price point, I haven’t found another place that matches its plating or food quality.

The menu is impressively diverse, the ambiance is warm and intimate, and best of all, they’re open until 11 PM on Fridays and Saturdays. For Irvine folks who constantly struggle to find decent late-night bites, this place is a blessing.

Whether you’re swinging by after work for a quick, comforting bowl of curry or unagi don, meeting up with friends for some bar bites and drinks, or coming specifically to enjoy the chef’s choice sashimi — this spot has you covered.

My personal favorite is the Hotate Crudo: a giant scallop as the base, topped with rich, fatty tuna belly, a perfectly balanced house-made sauce to cut through the richness, and a tiny dollop of caviar to bring out the flavors. It’s beautifully composed and seriously addictive.

The Salmon Don and Unagi Don are both incredibly hearty. For dishes that are just over ten bucks, the presentation is stunning — you can really tell the chef puts heart into the plating.

Since we had a group, we also ordered the Chef’s Choice Sashimi and Sushi. The portions were generous, the fish was fresh, and the chef even came over to introduce each type of fish — super friendly and passionate.

I especially liked the yuzu-seasoned black sea bream, which had a great texture and citrusy balance.

Don’t skip the sweet fruit sake! The pineapple and plum flavors were both refreshing and light — we’re already planning to hunt them down at the supermarket.

There’s also a daily specials board by the entrance and some solid lunch deals worth checking out.

Kopan Sushi is an absolute gem!
From the moment you walk in, the vibe is welcoming and modern, with a clean, minimalist aesthetic that lets the food shine. The sushi is incredibly fresh! every bite melts in your mouth. I highly recommend their Omakase selection if you’re looking to be impressed.

Service is attentive and friendly, and the chefs clearly take pride in their craft. Whether you’re a sushi connoisseur or just diving into Japanese cuisine, Kopan delivers quality and creativity with every plate. It’s easily become one of my go-to sushi spots!
