Kopan Sushi & Ramen - Ramen restaurant in Fullerton - 141 E Commonwealth Ave, USA

Absolutely the best ramen I've had, I had the Kara Miso Ramen and its got a good spice factor. Every server is putting their 200% effort and genuinely care for their customers. Will definitely be coming here more often. Lovely interior design as well. Update December 14th, 2023: Very lively on a Thursday! Enjoyed their Korusawa sake and sesame chicken! Sake is buy one get the 2nd one half off so come after 8pm for that special! Food as always is delicious and the servers are incredibly kind. My always go to for ramen or just a good night!

The place looks rad with Japanese decor and Japanese pop culture. Ramen at the shop I didn't enjoy as much as the other ramen shops I've been to for starters I only got HALF the egg 2 the egg isn't seasoned and 3 the yolk is not runny like it should. The pork chasu needs to have a sear and well define sear for that matter. The broth is thick, creamy, and fatty if that's how you like it you'll enjoy the bowl. Tempura and sushi were fine.

The ramen choices are 4 which keeps it simple but super effective. The service has never been below exceptional. We even got free beer more than once just because we're good tippers and we're always great customers. All you have to do is show up, smile and enjoy yourself with the best ramen OC has to offer.

The best ramen I have had in this area recently. The broth in the Kara Miso Ramen was so well balanced, perfectly salted, and seasoned. The pork chakshu was the most tender I have ever had. The Bento box my husband ordered was plenty variety. Miso soup was good and so was the salad. The sushi was soft, fish fresh and sweet. Quantity,quantity, flavor,service. Full points on everything.

Stopped by with a client who wanted to eat here. The broth for the Ramen is Pork based, so those who can't have pork, be advised. I went with Okinawa Sushi plate and it was good. Also had the squid balls which were very good.

I like how they are open late during this pandemic. The interior of this restaurant is great with nice decor with ambient lighting. Ramen broth and noodles are good but I was a bit disappointed that their chasiu (pork belly cut) was stale and tasted old & chewy. Also, the Takoyaki needs more octopus tentacle bits in each for a better and chewier texture. Kopan in Alhambra and Monterey Park is better in my opinion.

This rating is based on the vegan ramen only. The broth is bland, the vegetables are barely cooked, and the noodles are below average. This dish was so poorly executed I question the rest of the menu. Some of the servers are great, others not so much. The interior does have a really cool vibe, but I don’t think I would come back here again.

We were there last night to celebrate a family member’s birthday. We ordered Ebisu Sashimi 18 Pcs Cutlet Ramen, Kuro Mayu Ramen, Kara Miso Ramen, Senorita Roll, OMG Roll, Baked Green Mussel, Spicy Garlic Edamame, Salmon Roll, and The moon roll, they are super delicious and fresh! The only two orders that I don’t care for are the Crispy Scallop Roll and Popcorn Roll. Customer service was great. Highly recommended!!!
