Delightful, delicious, and surprising. They provide table service if you’re eating in, and then they cook it up fresh. The cook even helped me order since I was unfamiliar with a lot of the choices. One of the best meals I’ve had in a long time. Well done!

Disappointed. I ordered Tonkotsu Spicy Miso and it came with only a slice of chashu and some more without egg. I give 3 stars for the food because of the broth still nice.

I enjoyed my meal. It was close to the authentic Ramen I have had in Japan.

Tonkotsu Spicy Miso’s broth is good and perfect spice level for me. The only thing i didnt like is the chashu, its was too dry.

This was my first time trying J san. Im a fan of japanese curry so decided to try the fullerton location. We came on a Sunday afternoon and there was only one other family. So plenty of space. I can see it getting crowded easily during busy times. This is a sit down style place. We were given menus, ordered at the table, got food and paid like a standard resteraunt. So probably not the best if looking for a fast food style setting. We got chicken katsu curry and spicy beef curry. Both were delicious but if I had to rate it, it would be behind coco. The chicken curry wasnt all too spicy. Maybe mild. The beef did have a little kick to it. Each dish was $14. With two drinks and tip came to around $40 for two people. Not cheap but not the worst. My only real complaints were they left the front door open and flies got in and they kept playing the same song over and over again. Would recommend but there are definitely better curry places around.

Space is really small for a big family party... only 1 person working and he was doing everything from cooking ti taking the payments. My 1st time coming here. Food was okay but felt like everything was rushed. The only cool thing here was they had nice decorations around. The chicken was over cooked almost a bit burn.

Excellent food. Slightly overpriced but delicious!! Will definitely come back. I found this place cause it’s close to the yoga place we have been going to. So happy we did. It’s perfect. Ordered the Vegan Ramen from there — it came with the mushroom broth with amazing flavor.

Cute little spot tried it for the first time it was really good. I tried the chicken ramen it was very flavorful the beans sproud added a nice touch of freshness. Only down side due to the egg situation we didn't get our egg in our soup. But we will definitely be back.
