Great authentic japanese noodles in e boulder county! I think this is the only place like it within 20 miles of Boulder. Great, affordable food! Closed Tuesdays. read more

Went there today for lunch after having a doc appointment in the area. I ordered the chicken katsu curry and my partner ordered the unagi don, and some sushi. The sushi was alright, had the spicy shrimp and philly roll. The chicken katsu curry was nasty, I am not sure what kind of curry roux they were using but it was gross, and it was no where near the consistency of gravy as its supposed to be. The unagi don was small and mostly filled to the brim with garnishes with just a tiny bit of unagi and rice. The service was great, she was very friendly, but I don't see myself going back anytime soon. read more

WOW, DO NOT go here on weekend!!!! Our family went there last night with my kids and we waited over 30 minutes only to leave the restaurant... After 30mins of waiting, still no water and no high chair. What's REALLY crazy is that they have only ONE WAITER when the restaurant was completely full. I was so dumbfounded!!!! They REALLY need to hire some more ppl on the weekends! read more

I know the other reviews are a bit harsh, but what do you expect? You're getting sushi in a strip-mall right next to a China Buffet and a Radio Shack. I personally think the girl they have waiting tables is very friendly and accommodating- including letting us know when they have specials or deals on take-out. I've been eating here two times a month now for nearly a year and have never been dissatisfied with the quality of the fish or the temperature of the Sake (a common complaint of mine.) The sizes are generous and the price is right. If you are polite to the Itamae, expect better service and speed. Would recommend to anyone if they are looking for a reasonably priced sushi meal. read more

The review on 14 Feb 2014 written the Camera Dinning Critic, was a disappointment. The deep fried California roll that came with Bento Box was so dense with grease that one bite was more than enough for the meal. The Shoyu ramen was so salty and the ramen was hard and uncooked. I told the wait person that the noodle was too salty and uncooked, she replied, "The next time you can tell the kitchen that you want the noodles cooked and not to cook it too salty!" I don't think that is customer's responsibility to tell the kitchen to be sure the food gets cooked... We ordered 5 entrees between 3 of us and we all agreed that this Chinese run "Japanese" eatery didn't live up to the dinning critic Mr Clay Fong's praise. read more

Stopped by for lunch as the Pho place, around the corner, was closed. Wow! Food was great. I had the lunch bento box of pork katsu. It came with a small salad, miso soup, great sushi, rice, fried wonton, steamed veg and a nice lean piece of breaded pork. All was very tasty and I will be back. read more

Artfully prepared sushi. The "trust me" special was fresh and delicious and so well seasoned. Save room for the fried cheesecake. It is also a work of art read more

Looking for something different, we happened upon Udon Kaisha. Friendly staff, fresh sushi and yummy apps. We'll be back!

Delicious!! Very friendly staff and reasonable prices. Not sure what else I'm supposed to say, but yelp won't let me post it yet. Blah blah blah blah blah blah blah. read more

Not only do they have delicious Udon and Ramen soup with delicious broth and wonderful ingredients, but I was happy to also discover that they have excellent Sushi. I also had the Sweet Potato Roll and loved it. We also had the Spicy Tuna Roll which was also delicious. For dessert I had the Mochi Ice Cream, fantastic. The menu is interesting, creative and I can't wait to work my way through it. The presentation is also very nice. The staff is friendly, happy and so sweet. Be sure to check out the sign in the bathroom. It's so funny. Good sense of humor here! Plus excellent food. read more

Well, I might give it 4 stars because sometimes the noodles seem a little greasy (that is being very nit picky), however the service is excellent, friendly and fast, and they offer vegan and gluten free options. I frequent this place, and have tried others nearby. This is the only sushi place that has all of what I need, so I will continue to be a frequent customer here. read more

The food is decent. Truthfully, it doesn't quite deserve 5 stars, but I wouldn't give it any less. I ordered the bento box sashimi dinner and it was OK. It didn't taste bad, but the sushi grade was of lower quality and if you religiously eat sushi like me...you'll know when it's not really fresh. My fish wasn't firm and cool...it was a little warmer and the texture was too soft. Service was quick and waitress did a good job. This place gets busy and as you can imagine, it's a small establishment. They're probably understaffed, so I'd give them a break. I'll probably return and try some other things on the menu, especially the udon or ramen. read more

Excellent food. We had sushis that were great and the collar yellowfin fish was amazing. Their miso was also excellent, the best I have had. The space is small and could look a bit cleaner, hence the four star instead of 5. I will definitely come back. read more

Pretty good spot . We usually come for you can eat ( dinner 25$ per person ) . Salmon here is really soft and fresh . Sushi roll has good size. Give it a try !!!! read more

We picked up take out a week or two ago, I got an udon dish and my wife got a ramen dish, we were impressed with both. Looking forward to sitting down in the restaurant soon and really taking it all in. Go try it out!! read more

I saw Udon Kaisha's sign and thought that sounded really good for lunch. The restaurant is clean, the staff is friendly and the food was just what I needed. I'm no ramen/sushi expert, but it looked and tasted great - that's all that matters to me. The portions are generous for the price. I'll definitely be back! read more

I am super impressed with this place. Came in randomly since it was in walking distance from a friend's house. The prices for the quality CANNOT be beat anywhere between Boulder and Denver. read more

Awesome food, great prices, and excellent service. I love their ramen soups. I recommend the spicy pork with shoyu broth. It's only $8 and will definitely fill you up. Nothing beats it when you have a cold. For appetizer I really like the chicken gyoza pan fried. They also start you off with these delicious cucumbers in some sort of sweet vinegar. The decor is pretty basic but that's no problem with me. It's casual and I like it for that. The waitress that has been there every time for me is really fast and nice. Check them out. read more

We stopped here for lunch today while up in Lafayette. We all got different bento boxes including the sushi sashimi one. Everything was fresh and delicious. The service was great. Wish their wine was a bit better for a dinner possibility. But all was wonderful! read more

They have the most incredible fried rice I have ever had the pleasure of eating. Even as leftovers, my partner and I were blown away. When we picked up or order (we were way late) the woman was very pleasant and polite. We also ordered sushi, gyoza, and egg rolls--all of which were delicious. But seriously, that fried rice...we might eat is again tonight read more

Currently enjoying the Curry Udon with braised pork, bean sprouts, green onion and tofu. Spicy, rich and delicious with good portions for Lafayette prices. Support your local Udon / Ramen joint. read more

Best ramen I've had. We also had the vegan sushi roll and it was fantastic. You've gotta try this place

Delicious sushi! My husband and I went there with another couple last week, and all four of us were very pleased with the food. We particularly loved the fried rice, which we shared as an appetizer. Yummy and crunchy. We all liked our sushi so much that we ordered take out from there this week. The main problem is that there is a really small waitstaff and not much seating. So: service is pretty slow (although it's very polite and cheerful). I recommend eating at this restaurant--just not on busy Friday nights! The take-out was a great option, by the way, since we got a good meal but we didn't have to worry about packing into the small restaurant or fighting a crowd. read more

This little establishment is just amazing! Went for lunch and had a little bit of everything, The Udon was delicious, had baked mussels, spicy tuna roll and California roll. Everything was so fresh and tasty and all very reasonably priced. The wait staff was attentive. Will definitely go back! read more

I really liked the noodles. their service is really good, and the yakitori was delicious.

This is a really nice Asian restaurant. Very good sushi, reasonably priced, and some very innovative sushi specials. Try the sweet potato sushi. Noodle bowls are amazing. Can't say we've ever had a bad meal here; we go often, always leave stuffed and happy. read more

Came here on a Sunday since our favorite Japanese place was closed today. My husband's Sushi and Sashimi wasn't fresh tasting. My tempura was acceptable - a bit light on the panko breading - but I wasn't too happy that their Bento box only had vegetable tempura. They didn't do substitutions either. My son and I both noted that Miso was over diluted (not salty enough and lacking flavor). My son and his cousin both liked their dishes (Chicken Katsu and Tonkatsu). So overall, it was hit and miss for us. Some good, some bad. Won't come here again. read more

My wife and I came here spontaneously, A great hole in the wall. Cheap prices for amazing food. Never felt like we we're a burden to our waitress. She was very sweet and helpful. Many choices for gluten free. Labeled very well. And gluten free soy sauce. We will definitely be coming back here soon! read more

This place came highly recommended by a friend, but I have to say it was disappointing. The food was ok, but they forgot part of our order and I had to ask for it 3 times. Finally I had them box it up and took it home, I shouldn't have bothered it really wasn't good. They were super busy so maybe that is why the service was so slow. And I don't eat pork, which limited what we could order so maybe it would have been better if I had ordered something with pork in it? But I wouldn't recommend it based on our experience. read more

I too have lived in Tokyo, and I must disagree with the negative reviews here. Udon Kaisha is the closest I have found to the many small restaurants in Tokyo where I ate. I enjoy the food here, it is always well prepared, nicely presented, and tastes great. I moved away from Lafayette several years ago, but I find reasons to be in this area so I can stop in at Udon Kaisha. The Bento boxes in particular remind me of the time I spent in Tokyo. The prices are very reasonable. The service is good. I strongly recommend this restaurant. read more

I've never had better sushi. Make sure you give this place a try. You would never expect such good food from the location and the humble setting. read more

All I can say is two thumbs up. The foods and services were excellent. Very comfortable and cozy environment. I will come back again.

We visited this place twice when it first opened and were a little disappointed. Recently we gave Udon Kaisha another try and i'm so glad that we did! The house special ramen (I prefer the shoyu broth) is top-notch. I've only tried a few sushi rolls but all were fresh and high quality. We've also tried the fried rice, which is very tasty. The cucumbers in vinegar/sugar (?) they bring you at the beginning are intriguing. We've never had anything but excellent service here. Really great and such a treat to have in this Lafayette neighborhood. read more

Ate here for lunch, someone already mentioned how deserted it was - yep same thing today, 1 other person here. For appetizer we had the hiyayakko tofu, it was good but you really cannot mess up tofu too much. The other appetizer was takoyaki the dumpling was mushy. For the main course Dad had had the shoyu udon he said it was pretty good. Mom had the house special ramen, she said it was nothing special and could have made the same at home. When I saw her pick up the ramen w/her chopsticks it was in a clump so that means they didn't mix it while it was cooking. I had the kaisen don, the fish was in cut in thick pieces - I thought 'yea me' then I took a bite of the white tuna and it was slightly frozen. The tuna was a dull pink, so not very fresh. This is the kicker - I guess they're changing the look of the menu because this lady came in to discuss with the owner what she would like the layout to look like. Rather than picking photos from what the chef created and/or made, the photos are just different pics from the internet. My suggestion is to go a bit more north into Longmont and find much better Japanese restaurants. read more

Friendly and attentive staff. Had the ramen and some sushi rolls, both were great. Will come back soon!

My husband and I went here with a groupon and it was a great experience. When we pulled up the place was completely deserted. Our favorite Chinese place is a hole in the wall, so we knew that this place would either be really good or really bad. We loved it. Since we had a groupon for $40 we ordered a lot of food to spend the entire groupon. We got crab and cheese wontons, chicken gyoza, udon (I forget which one it was called. It had shrimp tempura), California rolls, and the fried bananas with red bean ice cream. The wontons were perfect. My husband is a bit picky about them, but they were a great balance of soft where they should be and crispy where they should be. The chicken gyoza were great. Our waiter was excellent. Since we were the only ones there the service was perfect. He was very friendly and polite and easily answered all of our questions. Redeeming the groupon wasn't a problem at all. We will definitely be going back here. read more

Wait staff was friendly, but unfortunately, I was not impressed with the flavor or quality of food that I ordered. I ordered a spider/soft shell crab roll and miso soup. I don't think this was a $12 roll, should be $8. Was expecting the crab to be warm inside as it was deep fried, but it was on the colder side. I recommend sticking with a bento box or udon as opposed to their "specialty" rolls. read more

When I crave for ramen but don't want to drive to Denver, I'd come here and order spicy pork in shoyu soup. Good enough. Seafood fried rice and grilled squid are the other two items I often order. I love their green tea smoothie when I feel like splurging. read more

Great noodle house in an unassuming location. Friendly attentive staff. Our family usually gets some combination of ramen, udon soup, fried rice, sushi. Very reasonably priced, reliably delicious, and good sized portions. We are regulars, visiting once a month or so, and we are thankful for a go-to alternative to other chain quick meal stops. read more

Great place for Japanese! Great rolls, miso, bento boxes. Absolutely love the Golden State roll! Service is great, was in their on a Thursday evening for dinner with my family and they kept getting bombarded with more and more tables but they still took great care of us! read more
