Kopan Sushi & Ramen — Restaurant in Garden Grove

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...

First time here. This place has got to be one of the worst ramen places out there. I came here with family, ordering a bowl of ramen each, along with 1 to-go for a roommate at home, with all 3 being the customizable type. Following our order where the server even wrote the order down properly, one ramen was brought out 30 minutes later and my own ramen was brought out after an additional 15 minutes. To make matters worse my ramen was not even correct to what I ordered. There was no hot spice seasoning on the side which was recommended in the menu if you weren't sure what level you could handle. However I never got that. There was also no ramen seasonings you traditionally see at other ramen places either. I told myself everything would be okay as long as the ramen tasted good. I was horribly wrong. The ramen noodles itself tasted like they had been prepared quickly to save time. Not only were they still stuck together in a big lump after attempting to separate them.. But some parts were not even soft! After finishing both our ramens we then proceeded to call someone over so we could pay. Again this took an additional 16 minutes JUST to get the bill! However, we got the wrong bill for someone else's table for some reason. After getting the correct bill, I checked it over and it was charged correctly gladly, all 3 ramens accounted for! And after we waited for a good 5 minutes with the bill ready, someone came by and took our form of payment and then I proceeded to ask for my to-go order which I ordered in the beginning. The reply I got was "Yea, it's coming out right now." So then we waited another 20 minutes for it! But it never arrived. Finally I had to raise my hand and ask about where it was. And then someone came by and was questioning whether we even ordered the to-go ramen! I cannot believe this type of service here... The receipt clearly showed everything and I was even charged for it as well. Finally, after waiting another 7 minutes the order of to-go ramen was finally brought out. No apology was ever issued to us for these terrible experiences at all. I will never be back at this place, a place which clearly cares more about speed and profits rather than quality and customer...

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...
