i20 Ramen and Katsu

I started to come to this place early this year. I can tell the quality of food went down. The udon was more expensive than katsu and yet it was so salty I had to ask for hot water. I never had issues with servers here. The food quality has gone down. Probably not going to be returning.

i20 is in the running for best spot for Katsu curry in SoCal! Great quality curry, Katsu is done exceedingly well, and their salads are great. The atmosphere in the dining area is calm and warm, and service is fantastic. I've gone enough that I'm recognized! I've brought most of my friends here and plan to continue visiting regularly.

The server was such a sweet girl I hope they treat her well! I didn’t get her name but she wore glasses and was serving all the tables on her own. She was so friendly and kind I’d go back just for her. Thank you for making my experience wonderful!

Oh no, bad luck. Our Saturday lunch got ruined just now. Ordered two ramens, both of which had bad wood-ear mushrooms, obviously tasted and smelled SOUR. Yikes! Had to spit out after a bite. I spoke with a lady manager, who tried to deny the fact. She did not even check what we were eating and said the mushrooms were fine and that only the portion we consumed might have gone bad. She didn’t seem to care about the food and service… charged half of the price on the bill. I don’t often put a one star review, but today is an exception. Hope I don’t get down with stomachache later today.

Yooo! This place was awesome. Such good food. And our server, Marc, was the coolest server ever. Such good vibes, very attentive, definitely brought his A game. This guy deserves a raise. Will definitely be back and hoping to be in his section next time we are in the area.

Toppings to my ramen were cold, which made the whole thing not as hot as it should have been. It was a much better spot before the tone change to being more upscale.

Really great for conversation. Recommend for date night. Ramen is excellent and so is the curry katsu.

Parking: Parking in front of the location can be difficult. Spots can get scarce. But there's always parking behind the establishment. You just need to walk down the alleyway.

Wow, this has got to be the best ramen I've had in recent memory! The spicy yuzu tonkotsu was amazing. So unique and complex. And the chashu was cooked PERFECTLY. best ramen meat I've ever had, maybe.

The single piece of scallop nigiri I ordered was similarly done perfectly. Soooo fresh. I can't wait to come back and eat more sushi, if the rest of their nigiri is this quality.

Highly highly recommend. Nice elevated vibe. Classy music, good mood. Could even be romantic – but not pretentious.

The cashier, an Asian woman who looks to be in her 30s or 40s, is very unfriendly. I see you are not getting fired. Are you the boss? I will never go again.

I left my glasses at the table and realized I forgot them. Drove straight back and came back 5 minutes past closing time. One of the employees (an older gentleman) was sitting in the back eating and we made eye contact. I tried to communicate that my prescription glasses were on the table he signaled me to go away. I tried to be as polite as possible.

This place is one of the best ramen restaurant in Fullerton. When I walked in, the atmosphere made me captivated. The staff were friendly too! I usually order the Spicy Tonkotsu Ramen, Tonkatsu, and Gyoza. If you kinda want to feel the spicy flavor, I highly recommend the Spicy Tonkotsu ramen. If you order a tonkatsu, they give you a lot, so I usually can't finish it all. Gyoza was also tasty too and they give you the soy sauce with it. Overall, a perfect place to eat your meal!

This is probably one of the top five delicious Japanese ramen restaurants in this neighborhood. When you open the door and enter, the atmosphere of the store catches your eye. The staff are also really friendly. I usually order spicy tonkotsu ramen, pork cutlet, and gyoza dumplings, and I recommend them all! There were two types of tonkotsu ramen, spicy and basic. I think the spicy one would be better for Koreans because it's spicier. The taste is really delicious! The portion of pork cutlet is large, so one order per person is enough, and the gyoza is served with soy sauce and is very juicy and delicious. I recommend it!
