Everything about this place is awesome. Fast service, great food, attentive staff, and lovely decor with a fun, funky, izakaya style vibe. It even has some communal tables, wood paneled booths, etc. Love it!! And the fact that the price is fair, sushi is great, the ramen broth (especially the black garlic tonkotsu with chili) is so good... you will leave full and happy. We came for lunch so didn't order drinks but the prices again look fair and their lunch and happy hour specials look top notch. Love the buttons to call your server to order, get more napkins, get a refill, get chili oil, or get a to go box. So smart. This is a great spot! It gets busy, though, so either get there early or be prepared to wait a bit (but again things move fast, it shouldn't be too big a problem).
I came here for the first time before a trip to Japan and the food and service is amazing! Parking was a bit difficult on a Saturday night, and we had to wait about 30 minutes, but it was well worth it! I love the atmpsphere, the service, the food...it was all five stars from me every time I've been there! Everyone that works there is attentive and helps everyone out, which I love. If a different server walks by and notices something, they ask and help out. I love that! I had a spicy tuna onigiri, spicy tuna poke bowl, and spicy tuna rolls (notice a theme?) and they were all great quality and oishii desu!
It was my first time visiting this place. Came here Saturday night and was super hungry. They were busy so we had to wait 15-20 minutes for a table. I really had my heart set on ramen so we decided to wait. When we got seated they took our drink order as we filled out our paper with our order. We got the gyoza as an appetizer and i got the black garlic ramen and ask for extra pork and extra egg side to add to it i had skipped lunch so i was starved. My friend got one of the curry ramens. Before the server took the order slip i clarified to him that the extra topping went to the black garlic ramen. The gyoza was ok nothing exceptionally different from other places i was satisfied with it. My friend got his curry ramen first and about 5 min after i got mine. When i was dropped off it look to me that i was missing my extra side of pork that i asked for and was charged for. He said it was on my plate. I see the egg which i was happy about but this looked like a normal serving of pork to me. My friend with his chicken and pork curry ramen actually looked like he had more meat than mine which is odd considering i asked for an extra side of pork. The waiter assured that the order was correct with my extra pork. The ramen itself was delicious i throughly enjoyed it but it didn’t sit with me well that i still feel i was charged for the extra pork and didn’t receive it. I should have been more vocal about it, but i didn’t want to make a big scene. Although the ramen was delicious not sure if I’ll be back due to me feeling like i was overcharged and underserved. You guys be the judge does this look like double pork to you?
Sometimes you just need a comfort meal of Ramen after a long day at work and a chilly night. This place is recommended to me and I’m pretty glad they did. The service was a bit slow, but they were also really busy. I decided on the peach Soju and the spicy chicken Ramen. They sold you was good, but it could’ve been better. Had it have been a little bit more tart. The Ramen was really good. There was a lot of big bold flavors, but also I feel as though it could’ve been a little bit more on the savory side seeing as it was a little on the sweet side. The spice was nice. I wouldn’t have mind something a little bit more puncher though, personal preference. I could see myself going back
⭐️⭐️⭐️⭐️⭐️ Authentic Japanese Ramen – A Hidden Gem in Aurora! As someone who visits Japan every year, I can confidently say Katsu Ramen serves some of the most authentic ramen I’ve had outside of Japan. The black garlic tonkotsu ramen is rich, flavorful, and perfectly balanced, while the curry ramen brings a comforting depth you don’t often find in the U.S. The pork gyoza are crispy on the outside, juicy on the inside—exactly how they should be. The portions are generous, the prices are very reasonable, and they even have unique onigiri options you don’t usually see on menus here. The service is fast and friendly, and the atmosphere feels like a cozy ramen-ya you'd find tucked away in a Tokyo alley—clean, relaxed, and full of charm. Definitely a go-to spot for anyone craving real Japanese comfort food. 5 stars for quality, cleanliness, atmosphere, and service!
