Was User at Osaka's a mag?
I recently visited this restaurant with my family while traveling in Colorado. I didn’t expect to find authentic Japanese cuisine in a shopping center, but I was pleasantly surprised. The staff was predominantly Japanese, and some wore traditional attire. They were friendly and polite, answering all of our questions about the menu. The selection was diverse and included many dishes that reminded me of my time in Japa... View all feedback.

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

The owner stopped at our table and told us the origin story of the restaurant. He was so friendly and created a beautiful restaurant. The food was amazing and drinks were good too. Service was also excellent and we enjoyed our Valentines Day here Meal type: Dinner Price per person: $30–50

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.

This was my wife’s first meal after giving birth and not having raw fish for over 9 months. The freshness of the fish was excellent and they provided us with plenty of gluten free soy sauce which is a nice bonus. The sashimi platter and seaweed saladwere also very nice. Would like to try more of their menu sometime soon it does seem pretty busy on Friday/Saturday nights.

Best Okonomiyaki ever!!! That is so worth to drive for 50 min and went there for my birthday dinner. The Okonomiyaki’s base I guess is mixed by egg white and cabbage, so it is really soft and moist. It has puffed rice as well, sooo good! The port bellyand seafoods on top are all matched and grilled so well. Agedashi tofu is also delicious. The skin is on the thick side but thesoup base is super flavorful, not too salty and not too sweet, but with dashi and seaweed flavor. I always ordered it and use itto judge a Japanese restaurant and it is definitely meet my bar. Ramen is also tasty! Also meet my bar.
