Kopan Sushi & Ramen

I just moved here and wanted to enjoy a nice hot bowl of ramen on the 1st rainy day in fall. I entered dripping and waited 3-4 minutes next to a sign that said wait to be seated. 3 out of 12 tables were occupied and eating but I eventually went to a sushi chef to check in. They said find a seat.
At a table, I eventually was greeted, handed a menu and ordered crispy rice, their signature bowl of ramen and a beer and asked it all come out together. A water was followed with the beer which was fine but then immediately served my bowl of ramen. Hungry, I dug in hoping for the crispy rice to follow as that is what I wanted to eat first.
The ramen looked nice but it tasted soulless and commercial. I tried took push past the cold ingredients but again, I was hungry so that was easy to do (the broth warm, not hot.) Half way through my bowl I asked about the crispy rice and it was brought to me after. It was decent for what it was.
Overall, I get it. I was 20 once not carrying about my job and how I performed but food service comes with the territory that people come in to be comforted with some nice service and good food. Neither was had here. I was served my receipt with a small apology and left.
I do plan on coming back as I get recommendations from people and maybe I ordered the wrong things. But, if this is how a slow time was then I'm not too confident on how a dinner service will turn out.

I love coming here as there is always space for any size party. The food is always a 10/10 and the service today was mediocre but it's usually good or better (3.5-5.0). You won't regret coming here tonight.

Tucked into a quiet plaza near a karaoke bar, this ramen spot is easy to miss but a lifesaver on cold nights. The tonkotsu broth was thick and creamy, with a deep pork flavor that lingered perfectly. I got the spicy level 2—it was hot but not overwhelming. Gyoza were crisp on the outside, juicy inside. The vibe is calm and welcoming, perfect for solo diners

If seated in the patio area, customers tend to be forgotten. Need to go over to the main restaurant to grab someone to take our orders.

Other than that, food was good. Price is medium to high due to cuisine.

The food was good and the service was excellent

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!
