Osaka's

Great restaurant to get some authentic Japanese food and try some new things! Service was kind, atmosphere was inviting, and we got to try some new to us Japanese dishes that made it fun! Huge options for drinks I had never experienced, the tea was delicious! I was able to try their burgers that they only serve on certain days and that is a recommended experience! Had a great time and would recommend this restaurant for anyone looking for some good Japanese food!

This has to be one of the best Japanese restaurants that I’ve been to, and that is no exaggeration. I had a small meal of takoyaki, edamame, and some assorted nigiri and it was outstanding. The cold house sake is very good as well. Highly recommend! Update: I came back again and had the ramen and sashimi and it amazing. I would give it a Michelin star if I could. A true gem! 💎

Luckily got here at 5pm (on a Sunday) because this place was reserved and fully booked. They had the Osaka okonomiyaki burger, which I really enjoyed with a spicy sauce. For the okonomiyaki to be more authentic, it was missing the Japanese mustard (which they had) and bonito flakes (which they also had) with an additional dried seaweed shake on top. I wonder if they altered the original recipe to fit the taste of the American visitors. It looked like the winner was the freshly fried tempura and ramen dishes. We'll have to come back to try it. Personally felt the sushi was well prepared (generous and skillful cuts), but not as fresh as it could be. I'd come back again if I'm in the area.

So good I went back again the next night! Delicious ramen offered alongside less known dishes like okonomiyaki, Osaka’s is a nice Japanese place with authenticity on the menu. Very friendly staff! I will definitely come again next time I’m in Boulder.

First restaurant I've found that serves okonomiyaki! Haven't had it since Japan! I liked it though expected them to chop up the seafood / meat and incorporate it into the okonomiyaki. The Osaka burger was interesting but thought the sauce was a little strong. Ginger for sushi tasted fresh and handroll was great!

Staff, owner and everyone in the restaurant are incredibly friendly and professional. It feels like a true family owned restaurant that employees respect. I had the Yuzu Ramen with Chashu Pork and an egg added. I worked at a ramen restaurant once so my standards are pretty high, and this bowl did not disappoint! I particularly loved the broth and tofu, but didn’t enjoy the pork. Tea after dinner was wonderful. The place was packed on a Sunday night, and the staff greets and says farewell to everyone that comes in and out. Lovely place for a meal.

Wow! We came here while on a trip after doing research on reviews and we were very happy with our decision. Excellent nigiri sushi, hand rolls and maki. The miso soup and hot sake was also really good. We had a nice table red wine. The menu is also very helpful in labeling what is gluten free. The service is prompt. They use an on demand electronic button prompt to notify staff when you’re ready to order. Great atmosphere. Oh and bonus land- they have heated toilet seats. Highly recommend.

Great authentic Japanese restaurant with quite an extensive menu option. We came on a Sunday night and it was already very busy place at 6pm. Only note is they charged us as a large party with automatic gratuity tip on our bill when we only have 4 adults and a young child. Maybe they have listed this somewhere but this is our first time experiencing a party of 4 (5 if they really need to count the kid) to be a large party. We would still tip generously but definitely caused confusion at first when paying the bill.

Everything about our experience here was outstanding - it was truly the best I've had in a while. We arrived at around 7:30pm without a reservation, and the place was almost full, which we took as a good sign! (Especially for a Monday night.) We were seated right away in one of the few open tables left. Our table of 4 shared mostly everything, which we highly recommend doing so you can taste it all! We started with a few appetizers and one of the scallion pancake dishes. We also ordered one of the sushi rolls and sashimi as a mid-course. Each couple shared a bowl of ramen, which felt like a warm hug to close out our meal. Each dish we tried was impressive, flavorful, and unique. Highlights (for me) were the takoyaki and black seaweed salad! This place has really great value, too. A meal at this level of quality in the Bay Area (where we're visiting from) would maybe be 2-3x the price! Our table also tried a few of their Japanese beers and split a bottle of sake, which added to the overall experience. The hospitality was overall impeccable, while also relaxed and oh-so-humble. An older gentleman, who I assume to be the owner, was very active around the dining room, assisting the staff, and following up with the tables enjoying their meals. The sweetest part was when he asked the whole dining room to join in singing happy birthday for a table there to celebrate. This level of hospitality, set by example, trickles down to every other staff member there. Everyone was so kind and attentive! This place is an absolute gem! If I'm ever back in Boulder, I'll be dining again!

Best Japanese since moving from CA four years ago. Their tempura and agedashi are delicious and light. Sushi was super fresh! Their Tantan men was delicious -- broth is super rich and flavorful. The Osaka's ramen was delicious as well -- the broth equally as flavorful as the Tantan. The noodles were chewy and perfect. They also offer okonomiyaki which we haven't seen since our visit to Osaka last fall. It's an hour drive for us to get to Osaka's, but we'll do it because the food is that good!!! p.s. the tea is great as well -- I love how they serve it to you in your own little beautiful pot!

THE TOPS! If you want a culinary adventure in a cute atmosphere with good service, come here! All the food was delicious, so let's talk about what sets this place apart. Highlights: Sincerely friendly staff The menu had so much variety to appease any pallet. Sushi, ramen, specialty dishes. Clearly market gluten-free and dairy-free options There was a device on the table to signal servers for when you needed something: to order, pay, etc. NO lowlights, but here is what to be prepared for: Timing: We were there on a Saturday and it got BUSY! Good sign for sure. But make a reservation, and be prepared to have the pace match the volume. It wasn't unreasonably slow by any means, but the kitchen was cranking out a lot of food. The sushi came out much faster than the hot kitchen food.

I have eaten at many us Japanese restaurants but this was so great compared to the rest. Food and drinks were great. Service was the best i have seen. Loved it so much i went twice

Nice service. Surprisingly great Japanese food and quite authentic. Tofu and modan yaki very good. Mille crepe also nice.

Great food, good service and nice ambiance. This was our first time at Osaka and we were not disappointed.

The best Japanese food in Boulder! I loved the okonomiyaki (wish they added fish flakes on it) since it was loaded with cabbage! The spicy miso ramen was rich. They were a bit busy when I came and had a bit of a wait even with a reservation but understandable since they were a bit understaffed. I love how they have buttons for ordering, needing anything else, and paying the check. It makes it convenient for the waiters and the customer. It's a well decorated and clean restaurant! A great Asian go-to restaurant when you're in Boulder.

We took my mother in law and her friend from Japan here and they loved the authenticity. We had sushi, eel, raamen, tea and deserts. The chef came out and chatted with our family in Japanese, which was lovely. All of the food was fresh and delicious, and plated beautifully. The restaurant is clean and spacious, and the food is a good value for the money. We would happily come back.

Every time I come to Boulder I eat at Osakas. I'm from Los Angeles and my son goes to CU Boulder. We originally found this place because we're Hilton memebers and this restaurant is a stone's throw from there. They open at 5 for dinner and it's always full. Ive written a couple of reviews already for this place. I still think it's exceptional. Their hand rolls are done extremely well, their salmon is juicy and their noodles have the perfect chew. I love this place and always look forward to coming back to Boulder so I can eat here.

As someone who has traveled to Osaka Japan, this place is some of the best Japanese food you will find and you don't have to fly across the globe. Their food and sushi are fantastic - mostly authenticity Japanese but some dishes have a Boulder / Colorado flare. Vegans will be very happy here. The atmosphere is just as Japanese as the food. Service is usually very fast, your server is only a button press away. Owner is adorable and is frequently seen around greeting guests.

Fun Fact: Okonomiyaki is a RARE dish to found made in the States! According to Osaka's menu, Okonomiyaki is: "a traditional, savory pancake made with wheat flour, eggs, and crunchy cabbage (or kale) with our original okonomiyaki sauce and Japanese mayo." If you're going to Osaka's for your first time, you have to choose one of the SEVEN Okonomiyaki to try. They each consist of the base listed above but all have different delicious toppings. There are options of pork, beef, cheese, seafood, veggie and combos. You can even get your Okonomiyaki made GLUTEN FREE! In our case, we tried the Butatama, which is Osaka's Okonomiyaki with Mugifuji pork belly, their OG okonomiyaki sauce and Japanese mayonnaise. IT WAS ABSOLUTELY MINDBLOWING FOR US & OUR TASTE BUDS! Originally, we had wanted to pair this with their famous Yelp Top 100 Burger. However, we found out they only make the burgers Sunday, Monday and Thursday. We pivoted, and tried three sushi rolls: Avocado & Salmon, Negihama (Fatty Hamachi & Scallion) and Negitoro (Bluefin Fatty Tuna & Scallion). It became a happy surprise to find out they also did sushi so well. It was fresh, simple and flavorful. Exactly how we like our sushi. Beyond the food, the service here is fantastic. We sat on the patio where each table had a clicker to let the waitress or waiter know we needed assistance. When we were ready to order or needed more water, you just clicked the button to alert them. It made for a really relaxing meal with minimal interruptions. Super cool gizmo & idea, I loved it! Finally, the coolest part of the meal was being thanked by the owner for coming in. I watched him go around to each table mid meal and check on their experience, as well as, thank them for coming into try his restaurants food. We've only been to a few restaurants that still do this type of service, and we really appreciate it. It always makes us feel very valued as a customer. (: I'll say one of the best overall restaurants I've been to in Boulder!

Osaka's is a full-service Japanese restaurant in The Village. There's sushi and many non-sushi items. Both sides of the menu are good. Sushi's more expensive. The non-sushi items are maybe not as well-known but are definitely worth trying. They have a button you can press to call for service. They do the irasshaimase thing (they yell "welcome"). There was a short wait (without a reservation). They seemed pretty full on a Sunday evening.

Some of the best sushi I've had. Tried the gyoza (4/5 deep fried), ikageso-age (4/5 not too heavy and well battered), the spicy miso ramen (4/5 just an all around great ramen), and the chirashi sushi box (100/5 I have never had such a delicious chirashi assortment with great fresh fish). Service was super fast and the place was overall great. I would definitely come again!

Had a lovely experience here for a business dinner. We started with the Edamame. Although it says sea salt I don't think they had any added. We had to request our own. I ordered the Chicken Teriyaki with white rice. It was delicious! Our service was fantastic and our food was served quickly, Definitely worth noting that there are NO free refills on sodas.

The food here is really good and the staff is service oriented and friendly. The restaurant has a great ambiance and is clean. The only negative is the place is very busy so you should get your name on the waitlist.

This is a hidden treasure I cannot wait to be back. Authentic food, kind people, and a great atmosphere. Pro tip: Make reservations, but if you do/don't and there's a wait - hang tight - it is SO worth it!! (I know we can all get hangry, but please be kind - let's support our local businesses!)

What a find! Are you looking for that authentic flavor from the Land of Rising sun in Boulder? If so this is the place! A VERY wide variety of different Japanese dishes: Ramen, yakisoba, teppanyaki, pancake dishes aka okonomiyaki, raw fish aka sushi, Osaka burger?? etc, etc. I 100% agree that this is very authentic to the dishes and flavors I found while in Japan SHUSHI there are No fancy "US inspired " overflowing mega rolls with lemons or sauces or baked or deep fried, just standard Japanese styles of maki rolls, sashimi, chirashi and nigiri rolls Agedashi Tofu was spot on! Strongly recommend Fatty tuna and yellowtail makis and large pieces of hamachi for the jalapeño carpaccio. As you would expect Miso and edamame were good We Tried the Butatama, never had that before. Wasn't my favorite dish but well done. The service and ambience are as reported in other reviews. We were there on a random winter Monday and got a table but still quite busy. Strongly recommend calling to make a reservation. Again, this is an experiential meal and if you want to be transported to Japan for the evening come here!

Osaka's has improved even more since my last outstanding experience. The service was fast, knowledgable, and friendly. The food was delicious (okinomiyaki is still a favorite) and fresh.

Was in town for a hike and wanted to grab ramen after. We saw Osaka had great reviews and thought we would try. We arrived around 4:25 and there was already a line outside which reaffirmed this place was good. We were able to get a table for two without a reservation and so happy we did! The place is cute and clean inside, also offers additional outside seating in the front. They had a full wall of spirits when you walk in and towards the back was their sushi bar. We started with two sushi rolls, spicy salmon and avocado and cucumber. For an entree I ordered their Spicy Miso Ramen. Everything was so good and the service was so nice. Great overall experience, would definitely come back!

This place is delicious! The sushi was very good and the pork was so tender it melted in your mouth.

A fantastic place to visit! Food was a little pricey, but definitely well worth it. We had some who lived in Japan and they said the meal was as authentic as it gets. All the fish tastes fresh and not at all like frozen. The spicy miso ramen was delicious. Service was good. It took a little while to get the sushi itself, however it was worth the wait. The himself came to the table and asked how the meal was which we thought was amazing for someone his age. Atmosphere was fantastic. The decorations were simple and nice, and even down to the dish-ware was thought out.

I am an enormous sushi fan, and this is objectively probably the best sushi meal I have ever had. The fish was so impressive and fresh. I started with two orders of nigiri, maguro and aburi hamachi belly, and followed that with two hosomaki (thin) rolls, the avocado & cucumber maki and tekka maki. The perfect portions! Each bite was better than the last. It was fresh and fantastic! I will return every chance I get! Recommend x 100%!

New favorite Japanese restaurant in Colorado!! Pretty, clean, authentic, and delicious!! My favorites: - obanzai set The pickled eggplants, peppers, and root plants The sweet pickle flavor really brings out the best side of the original flavor of the ingredients - agedashi tofu Such rich flavors! Glaze on the outside, and tea in the soup, and crispy shell, with super tender tofu inside Other good stuff - butatama - osakas ramen (the pork was extremely delicious) - hot sake Will definitely come back and try more dishes, especially cocktails, sashimis, and katsu!

At first we were really excited to see such an "authentic" looking Japanese restaurant. The waitresses all look great in their kimonos. However, their "calling by a button" system doesn't work very smoothly. We kept pushing the button and nobody showed up until we had to physically flag someone. Osaka's has the best "boring sushi", aka, simple roles like salmon and tuna. Just a dot of fish in the middle of a seaweed wrapped roll, looking very much like a Japanese flag. I say they're the best because you can feel how tightly packed the sushi rice was, as well as the perfect amount of vinegar. They tasted so fresh. I call them "boring" because they aren't that fun to eat: as opposed to sauce and topping heavy "special rolls" that are totally Americanized and not at all Japanese. But I'm used to what I'm used to, aren't you? ;-) The ramen was ok, the okonomiyaki (we had the Gyutama with beef) was ok. The dessert (we had Mont Blanc) was ok. Overall it was a little above OK, so it's more like 3.5 stars for me.

Excellent service and very authentic ramen. Restaurant was very clean. Family that runs it is very sweet.

The best and probably only place in Colorado for authentic okonomiyaki. I love the shiso negi one. Always comes out sizzling hot and delicious. Highly recommend this amazing authentic Japanese restaurant run by a sweet Japanese family.

Since moving from Chicago, we have been on the lookout for okonomiyaki in Colorado and finally found one in Boulder- it did not disappoint! Would highly recommend the vegetable and cheese okonomiyaki- so flavorful and unique. The miso soup never misses and don't pass on the matcha puff (one of my favorite desserts) The owner is so nice and comes around to check in and hear the history of why he opened the restaurant (very interesting)! All the staff were nice and the presentation of the food/drinks is so cute . Overall, we will be back to try their sushi and get more okonomiyaki! Definitely a new date spot

I was in Boulder recently on vacation and decided to try Osaka's. I ordered the teriyaki chicken . It came with strips of chicken marinaded in teriyaki sauce along with seasonal vegetables. I really enjoyed the flavor he the teriyaki. The vegetables were also very tasty. Overall, if you are eating at the restaurant and looking for something to order I would highly recommend the teriyaki chicken.

Amazing food and service with good vibe! Our favorite spot in Boulder. Owner is great!

I would eat here every single week if I could afford it. Authentically Japanese in atmosphere and menu. This place caught my eye because it serves okinomiyaki's which are pretty hard to find (and a pain to make). Tucked away in a shopping center of home design shops, this popular place was hopping on a Saturday night. My sister and I split the Obanzai Set of 3 seasonal vegetable dishes, Takoyaki Octopus Balls and the Modan Yaki with pork belly, yakisoba and egg. All dishes exceeded expectations and were served traditional Japanese style with minimalist artistic style. I am obsessed with authentic healthy Japanese food. I have found these little gems hidden in some of the most unexpected places in the USA. I am so glad I discovered this restaurant and will definitely be a regular patron because I cannot live without Japanese food.

The ambiance and staff are amazing. The food was tasty and authentic. We had sushi, ramen, and tempura. Looked like they had a large selection of saki and some nice cocktails as well as a variety of teas, although we didn't order any. Maybe next time.

I've only been to Osaka's once, but everything we had was fantastic. The takoyaki and okonomiyaki were the best I've ever had and I can't wait to go back for more. There are many other things on the menu ai'd like to try, specifically the vegetable burgers. The owner is very nice and came to our table to chat with us. Looking forward to returning, the food was some of the best I've tasted in Boulder!

We tried Osaka's for the very first time tonight and we were completely wowed! From the moment you walk in, you're greeted by the attentive staff with a friendly Irrashaimase and a warm ambiance of modern Japanese decor. Pictured below, the Negishio Garlic Ramen was my dish of choice and it did not disappoint. This ramen was the best I have ever eaten even in Tokyo. Each bowl is a work of art made with high quality ingredients and flavor combinations that are nothing short of perfection. The noodles are springy and perfectly cooked, just the way they should be. The tender nuggets of chicken, scallions and red ginger combined with the port bone broth, all added their own unique flavor and crunchy texture. There were plenty of staff all working diligently to provide impeccable service and the restaurant was hopping with customers. You can tell the owners have really poured their heart and Japanese culture into every aspect of this restaurant. After one visit we are hooked! Next time we will be back to try the endless menu options of sushi.

I was very underwhelmed by the sushi. The gyoza didn't have much flavor, and sushi was bland.

Decided to try Osaka based on reviews here and I could not have been more disappointed. Party of 2 on a Sunday night with reservations. Seated right away by a friendly kid who explained the menus (yes 4 menus) and table call buttons for service. So we hit the button for service right away, hit it again, and again, and again, watching the tables around us get food and drinks. 20 minutes after being seated, a frantic waitress shows up and finally takes our order. I'm skeptical of sashimi at any new place so I always order the Hamachi, Salmon, and Red Snapper sashimi because in my experience those 3 pieces will you give you a very good idea of what to expect from the fish menu. We also ordered an Unagi roll and 2 beers. 1st round of beers came out pretty quick after ordering, so after 30 minutes, we finally have our 1st drink and an order in, should be quick right, 9 pieces of cut fish, and a simple roll. Another 30 minutes go's by and we finally receive our 1 roll and 9 slices of fish. I'll go from light to dark fish.. Lightest was the Red Snapper, before the bite even hit my mouth I inhaled what tasted like a fishy burp. Once the slimey chewy fishy meat actually hit my mouth I immediately wanted to spit it out. It was so chewy I continued to try to just get it down without throwing up. I should have stopped but figured it couldn't get worse than that so I moved on to the Hamachi. The Hamachi was also very rubbery and chewy and surprising lacked any real flavor. It tasted like dirty water. So finally on to what was supposed to be Salmon but had the coloring of Caucasian skin tone and a shine from the slime that had grown on it. If you know what really low guality FARMED Salmon looks like, then you can perfectly envision this sad, gross piece of Salmon. Yes, I did actually try to eat it and it was absolutely the worst bite of sashimi I have ever had anywhere in my life. Disgusting. My beer was long gone at this point, and our server button had been pushed many times with no response. So I swished the last remaining drops of water from my empty water glass around in my mouth in a febrile attempt to wash away the sushi diarrhea I had just suffered. Paid our $88 bill and left with utter disappointment. My date said the Unagi roll was ok. Whatever you do, DO NOT ORDER SASHIMI

Excellent food and service! Authentic Japanese cuisine, sushi and appetizers. We frequent this place regularly.

Always a wonderful experience and the best ramen olive had in Boulder so far! The staff is helpful and courteous.

So I was originally going to give this place a 4, however I have mixed feelings as I think this place gave me some food poisoning. I had the worst stomachache/felt super nauseous a few hours after dinner. However, here's my experience when I was at the restaurant. The employees were so friendly and they had this high tech device that allows you to easily communicate with the servers what you need before they get to your table. We tried the Takoyaki and I got the Pork Yakisoba. Both were very yummy and the flavors were great. My only complaint was that the food did take a while, but at least you knew they were making it fresh.

This is the most authentic Japanese restaurant we have found in Colorado. Their sushi is great but go to the things you may have never tried and you'll have a great meal. The ramen is even great. The range of dishes Osaka is able to do is quite impressive. Their sake selection is even great. The owners grew up with this food and take great pride in their restaurant and you can tell.

I took a stroll around my Boulder hotel, when I stumbled upon this special little place. Authentic Japanese cuisine tucked away in the foothills of the great Rocky mountains. They do ramen, they do yakisoba, they do teppan yaki, and they do okonomiyaki. But the real star of the show is their sushi bar. This is "old school" sushi, no fancy dressings or sauce overwhelming the sushi. Just rice, seaweed, and couple of ingredients. The quality of the proteins and the freshness of the produce make their sushi a symphony of simplicity.

This Japanese restaurant is well known on Yelp lol. The environment is nice - clean, automatic, well-decorated. 4 stars. Both dishes deserve 4 stars, just as good as it is expected.

This is honestly the best sushi in Boulder, hands down. Authentic and delicious. Their seared hamachi belly and black snapper nigiri are amazing. I'd recommend coming here if you want good quality nigiri or sashimi. Rolls are great too but the quality of the fish doesn't need to be hidden behind heavy sauces or fried ingredients, like many other Americanized sushi places. The gyutama okonomiyaki is also incredible. The owner Koji and his family are so friendly and welcoming. They make you feel like a part of the family.

Food is OK. It's a nice ambiance. Food takes forever and orders are inaccurate. I wouldn't come here if I am hungry. Maybe get a larger grill...

The Osaka Hamburger is not to be missed made with their special Japanese pancake and special bun! Your choice of filling of meat or special mushrooms.

I ordered takeout sushi here on a Sunday, when unfortunately a lot of the other sushi places are closed. I could not have been more disappointed--the portions were tiny, sushi was badly prepared and falling apart, almost no soy sauce was provided, and worst of all it was WAY overpriced. It looked and tasted like grocery store sushi. I DO NOT RECOMMEND this place for sushi.

The food here is amazing! After coming back home from Japan, I had been craving authentic Okonomiyaki. This place is very authentic and tasted exactly like the real thing, also the Tokoyaki is the best I have had in Colorado and it reminded of my time in Japan. The owner is from Osaka and you can tell by the incredible quality and taste of the food. Everyone was so friendly and the service was great, I highly recommend this restaurant to anyone who likes authentic Japanese food!

Gotta say, was thoroughly surprised and impressed by this gem of a restaurant (and its genuinely caring owner). I'm half Japanese. This place would make my mom happy. Get the okonomiyaki...super rare to find a place in the US that does it well.

Truly wonderful. The quality of the fish and all the food was amazing. The family ownership and hospitality is hard to find these days. Will definitely be back!!

What a fantastic meal! Lovely restaurant, friendly waitstaff, and excellent okonomiyaki. My husband and I are very familiar with okonomiyaki that we discovered when visiting Japan a few years ago and were thrilled to discover its existence in Boulder! This is an excellent restaurant and when we dined there on a Sunday night, Koji (the owner) went to each table to chat with the patrons. He is a delightful man and this made the experience for sure. Cannot wait to go back!
