“ Fantastic location for ramen, sushi, and various Japanese alcoholic beverages. They also have some beer options and several non alcoholic drinks. Super chill place, the music isn't too loud and they had a waiter on standby within earshot ready to help with anything. My buddy and I got some of their strawberry sake, which was chilled and tasted amazing. Would highly recommend. ”

“ 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! ”

“ 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. ”

“ The think this might be the best Japanese place in OC. The picture menu is awesome and fun to study. There is so much artistry, quality and value. The staff are obedient and cute. I splurged on myself. You feel like you are in a real back alley of Tokyo —the atmosphere is authentic. I keep coming back... ”

“ I think we have finally found our favorite sushi spot (and they also serve delicious ramen). The quality of the fish is very fresh. The presentation of each plate is neat and done with great detail. The service of the staff is very attentive. Had a very lovely experience and I will definitely be returning to try more items on the menu. Enjoyed some rolls, salad, ramen & crispy rice w/spicy tuna. Loved every morsel. Clean bathrooms. Quick service. All and all, very pleased. ”

“ I had a really great time today! The service was exceptional. We were served by Mia and Joanne. Mia helped us navigate their big menu, and offered lots of suggestions. She told us she just started, so we were so surprised by her GREAT service! 10/10 experience, thanks Mia and Joanne! ”

“ Don't judge the exterior facade by its appearance. I thought it was just a typical Japanese restaurant, but when we went inside, I said, "wow, this is a great and cozy place to eat." Food was great. But I must share, I still need to taste their ramen, just my mom. I ordered a bento (I don't have a picture, unfortunately). But, I loved everything. Will be going back. ”

“ I recently dined at Kopan Sushi in Garden Grove and the food and quality of fish was outstanding. My wife and I love eating sushi and we’ve been to quite a few spots in OC. This spot was definitely one of the better ones we’ve been to. You know it’s good when the sushi counter is right up front and the sushi chef greets you immediately upon entering. We had a great meal one here and would definitely come back! ”
