    Restaurant interior
    Daniel P.

    A friend and I have been wanting to get Concept 23 for a while, though their hours have never aligned with our meal time. We finally got to try it last week for lunch and I was very pleased with the service, quality of food and design of the restaurant interior. I chose the pork katsu bento box which was reasonably priced ($12.99 or $13.99) and came with soup and a salad. The bento box was out in less than fifteen minutes and it was a nice helping of food for the price! The quality was good and I will definitely return for another meal here.

    Hostile Server

    I'm leaving this review not just because of terrible service, but because what happened afterward crossed a line. Our server was openly hostile from the moment he asked us if we had our drink order ready. On two occasions he asked us something and would walk away if we didn't respond quick enough without making sure we had all ordered what we wanted. He offered no refills, never checked in, dropped to-go boxes and a combined bill while we were still eating, and told us he "couldn't" give separate checks because he was too busy and told us to just have one person pay and have the others pay through Zelle. He said we could wait until he was done serving all of (maybe?)five of the tables in the restaurant and then rushed me when I offered to pay the tab. Completely unprofessional, but unfortunately not the worst part. When we left, the server followed us outside and approached our vehicles in the parking lot, aggressively confronting us about not leaving a tip. He walked right up as we were pulling out, raising his voice and complaining about his $2/hr wage. No customer should ever be approached at their car. That behavior is intimidating, unsafe, and unacceptable in any business. My dashcam recorded the entire interaction. Afterward, I checked their reviews and noticed the "owner" May responding to reviews which happens to be the same name on the receipt he gave us. If the owner is the one chasing customers in the parking lot, that's seriously concerning. For anyone considering eating here, please be aware. This wasn't just bad service, I felt uncomfortable and unsafe. I strongly recommend choosing another restaurant.

    We love this place!!! Crab Rangoon is the best around, we've tried a handful of their rolls, loved them all. The options on the menu are plenty. We live in Gladstone and make the drive to Lawrence at least once a year to indulge

    Snow crab, and jalapeño roll

    My favorite sushi spot in Lawrence. To be honest I am not sure I have had better sushi anywhere else!! We started with a couple appetizers and then two rolls. The service was service was excellent and very quick. The ambiance is to be expected. They bussed the tables very promptly!! I would recommend dining in to go!! Please give this Mom and Pop a chance!!

    Gumbo and rice; good eating!

    Finally tried this restaurant out. The food was good and the price was fair. The staff was attentive and available when I needed em'. The place needed a good dusting though. I ordered the gumbo and egg rolls. I would recommend this place!

    Four different kinds of rolls.  Boston Roll, Snow crab and avocado, Salmon and Avocado, Tuna and cucumber.

    Stopped in here on a Sunday evening after having seen it as we drive by here a lot. Very happy we stopped. They have a terrific selection of sushi and rolls!! The crab rangoons are FANTASTIC and worth the trip all by themselves. I'm not a huge sushi fan, but this was very very good and the service was excellent. Can't wait to come back and try some of their more traditional meals!

    I had heard about this restaurant for my sister and we thought we'd give it a try while I was visiting her from Arizona. We arrived at Concept 23 around lunchtime The lunch menu was impressive. I order the lunch special. Miso soup, a salad , a golden crunchy roll, 2 crab Rangoon's and white rice. The main course was 5 big Shrimp Katsu . The meal was delicious. The service was top notch. This place is must when in Lawrence, KS.

    Waited 2 hours, finally had to get the food to go. Not worth it. Won't go again. Very disappointed.
