    Bang Bang Shrimp Fried Rice
    Samara S.

    Got the bang bang shrimp fried rice to go and it was phenomenal! Hope to be back soon

    Drunken Pork Noodles
    Mandy H.

    This restaurant feels like new Japanese, a western twist. We had the crab cakes, which were delicious with a side of roasted beets and edamame. We also had the drunken noodles and the spicy chicken steamed buns. I will say that the portions feel small for the apps and buns. Entrées are filling. Some of the meat in the drunken noodles were tough, others was nice and soft. Service was good. Ambiance is small and feels quaint, they have a patio outside in the back. 8/10

    You can find Kaizen at 127 S Central Ave Knoxville, TN 37902. This is in Knoxville's revitalized Old City. There's some street parking but most of it appears to be pay-to-park. There are several nearby lots also pay-to-park but some may be free on weekends. Kaizen appears to me to be more akin to an Izakaya than a noodle hosue, where you basically go for drinks and they supply some food to keep things going - it has a more expansive menu than an Izakaya (which tends to be yakitori and sushi) - Kaizen's menu features several noodle dishes which all looked very interesting. We started with the appetizers and ordered some mixed steamed buns and soup. All of the buns that I tried I liked quite a bit - some strong, distinctive flavors. For an entree I ordered the Koji-Cured Ribeye medium-rare - 12 oz sliced ribeye, gai lan, broad bean paste, steamed rice. The steak was cooked perfectly. The service was exceptional - the next night we tried Fin-Two Japanese Ale House across the street - this restaurant was my preference - the flavors seemed more authentic and the quality of the dishes better in my opinion.

    Bang Bang Shrimp Fried Rice

    I went here on a Wednesday night. I found a paid public parking lot across the street which was super convenient except that the price to park was a bit high so you may want to plan to go early to drive around to find better parking. We were able to be sat quickly without a reservation that day which was lucky and nice! Lots of choices on the menu and great for sharing! We started out with our own Bao buns. I got the mushroom one and it was very good!! We both shared the dry fry eggplant which were like fries and had a good spicy kick to them. Very delicious. We also got fried rice with bang bang shrimp. It came with an over easy egg that we broke before digging in - yum!!! Lots of flavor and very good! I'm excited to come back and try more items from the menu!!

    Mochi buns (bang bang shrimp on the left and shitake mushroom on the right)

    Cute little Japanese restaurant in Old City. Service was good and the food was between 4 and 5 stars, but I'll go with 4 (for reasons explained below). We went for lunch, which they serve on weekends using the same menu as for dinner. It's nice that they offer many "tapas" style small plates, so you can try various things. We started with the red curry crab cakes. The cakes were tasty, although we didn't get a lot of red curry coming through. They went well with the beets and edamame served along with the crab cakes. It's a nice combo both because you get sort of a side salad to balance the crab cakes, and because the beets and edamame are great when shared in the same bite with a piece of crab cake. Plus visually, it makes a beautiful dish! Also beautiful were our mochi buns, one bang bang shrimp and one shitake mushroom. Both were quite tasty, but the bang bang shrimp was my favorite. We also had the noodles with chicken and lemongrass teriyaki sauce. This one was a little disappointing. It wasn't bad and it got better as it sat for a little and the flavors melded together more. But again, we got zero lemongrass coming through in the teriyaki sauce. The sauce itself was a little too salty. The chicken (thighs) also could have been better. The noodles were good and the saving grace of the dish was the crispy wontons on top, which provided a nice contrasting crunch. Overall an enjoyable experience, but a little mixed.

    Drunken Pork Noodles
    Isabelle Z.

    Overall quality was fabulous and portions were perfect! Spice level on this drunken noodle with pork was higher than expected with all the chilli in it but overall flavor was top tier! Would definitely go here again, the appetizers looked great also.

    We finally made it over here for lunch on a Friday. We ordered: Sesame Salad: fresh, beautiful salad ingredients. The egg was perfectly cooked and the sesame dressing had a great base of flavors...just not nearly enough salt and seasoning. Loved the egg the most. Bang Bang Shrimp bun: this was tasty. The bao was so soft and delish. Wish there had been more cabbage Pork belly bun: we won't order this one again. Half was chewy and inedible. The risk you take with pork belly, though. Shrimp fried rice and Pork belly fried rice entrees: identical except for the protein. The shrimp was unfortunately very overcooked in this dish (but wasn't on our bun). The pork was again, hit-or-miss with what was edible. The meaty bits we did get were crisp and delish! The rice itself was amazing and the egg a perfect sauce when broken over top the dish. One of my favorite parts of our visit? When I cleared my rice into a takeout box, my plate had a cat on it. So cute! Love the lucky cat theme throughout.

    Spicy Chicken Steamed Bun
    Jordan A.

    Went here last week and loved it so much and will be going back. Menu is clearly labeled gluten free and t was such a cute building in old city Knoxville! Will be coming back here again the service was very friendly and very quick. Got the fried rice with grilled chicken and it was so yum.

    Fried Chicken Rice Bowl ($17)
    Ame G.

    We ate here for an early dinner and enjoyed it. We were dining with our small dog and love that they offer a dog friendly patio outback. Just check in at the front, and a staff member will escort you and your dog straight back to the patio. The patio was nicely shaded and had fans going. This helped with the evening heat and kept the bugs away. Service was quick and friendly. We decided upon a roasted pork belly steam bun ($3.50) to start and a roasted pork belly fried rice bowl ($18) along with a fried chicken rice bowl ($17). The bread of the bao bun was soft, and the pork belly slice with sauce was tasty. Both fried rice bowls were good, although, personally, I thought the pork belly in the fried rice bowl was a bit dry with hard bits of texture. Almost like it was cooked and then deep fried. I was lucky that pockets of pork belly fat helped to "rehydrate" the meat texture so to say. Nonetheless, the service was great, we enjoyed what was offered, and we loved sitting outside. Would recommend you give them a try.

    Lemongrass Lemongrass Teriyaki Chicken Noodle
    Katie G.

    I ordered the lemongrass chicken noodle dish. It was delicious! I cannot recommend enough. The food took a minute to arrive, but it was worth the wait.

    Mushroom-Shoyu Noodle
    Riley K.

    Amazing experience -- delicious food, great vibes, and exceptional service. Couldn't have asked for more!

    Duck Noodle Soup
    Danielle R.

    The duck noodle soup is definitely something to write home about. One of the most unique menu items I've had in some time. Amazing flavor! The atmosphere was cozy and inviting. Service was a little slow but the great food made up for it.

    Shrimp steamed bun
    Andy H.

    Food was great. We had a bunch of appetizers to get going and they didn't disappoint. Shrimp steamed buns were excellent. Eggplant was great but be careful there are some peppers hidden in there and they are SPICEY. Wings were crazy good. Wouldn't have thought watermelon and tuna went to together. IT DOES!! Get it. Tomato salad was great so I'm told. Fried was was fantastic along with the drunken boneless. Mochi to finish it off.

I just know the person I was with had it. We sat at the bar and the ambiance is really intimate. I have read now after being home that I guess they hide drink recipes in some of the books? I am not sure if that is true or not. If you can get a seat at the bar, it's so fun. Trey was great, as were the ladies! Trey puts on a little show with each drink he crafts. The drinks are ridiculously good. I would not be able to choose a favorite. I have no clue what the bill damage was, but I can say that between the both of us, we had every drink on the menu. Now I need to find reasons to go back to Knoxville just to go to the Peter Kern Library!

When we walked in, she glared at us as if we had interrupted something. She didn't greet us, didn't ask what we'd like to try, only gave us one word answers to any question that we asked. Never once smiled or tried to engage us. My friend was so frustrated with trying to get information from her that he stood up and almost walked out. I kept trying to engage her and even complemented her cute dress. Nothing. Stone face. I wanted to try the amaro flight and asked for it. She prepared it, set it in front of me, and said "so you'll want to close out now?" I told her "yes, that would be great, when I'm finished with my tasting". She proceeded to lean up against the bar with her back to us and didn't say another word. I had to get up and walk to the register, and when she finally turned around, I asked her "have we done something to upset you?" She said "no, why?" I said "because you seem REALLY annoyed that we're here". Her only response was to turn the register screen around and tell me the total. I'm so sad about this because I really wanted to taste other items and get a cocktail, but she was SO unpleasant and we felt SO unwelcome., Seeing all of the other great reviews, I can only imagine that they were with other people. I wish those other bartenders had been there.

They sell bottles of varying sizes at the bar and also at other places around town, including Total Wine. We love that they offer sampler flights with different liquors and also different size pours. They give you a tray with a sheet that describes the flavor profile for each offering. We also were given slushy samples and a customized gin sample, mixed with another shot to sip. We ordered slushies to enjoy on the patio and a flight with Hi Rye Whiskey, Ginferous Gin (favorite!), Uproot Gin, and Barrel Rested Cacoa Liqueur. I can't believe the differing flavors they can produce within the same type of booze. Masterful! The bartenders are friendly and so dang knowledgable. We purchased a bottle of Ginferous Gin and have kept the party going at home. Can't wait to go back! What a cool spot.

Service itself was good and the drinks were just okay. I like that they have many cocktail options to choose from, but my drink was honestly straight juice. As someone who's lightweight, I was shocked to find that the portions for drinks for the little amount of alcohol for $15 is a bit absurd (I got the st Richard ride). I'd only come once for the ambiance but it's pretty disappointing for what you pay. 6.5/10
