My waiter was amazing and really went above and beyond, helping with the high chair (and sanitizing it for me), kids plates and drink cup, and swooping in within 30 seconds of a massive spill my baby made. SO impressed. The food was just as impressive! Order via a tablet at your table, and it sends the order to your waiter who confirms it. Their Chicken karaage appetizer was crisp outside and juicy in the center with great flavor. Their Wagyu Curry was great as well, with tender wagyu pieces and a nice curry base. Their chicken katsu curry was also perfectly cooked and tender as well. Will need to come back for dinner as no sushi at lunch.

Visited on a Sunday afternoon and was seated right away. The restaurant is on the smaller side,…read morewith both bar and booth seating available. It felt a little stuffy inside because of the hot weather, but they had a floor fan that helped cool the space. Ordering is done through an iPad, which made the process quick and easy. I ordered the Tonkatsu Curry with medium spice. The portion size was small, but the curry was flavorful with a noticeable kick, as I ordered medium spicy. The tonkatsu arrived hot, crunchy, and tasty. There is a parking lot in the back, or you can try to find street parking in the front. Service was a little slow toward the end of our meal, as we had to wait for our check and to-go boxes, but overall, it was a good experience.

This was such a great restaurant for a Sunday lunch! My family and I all wanted different things…read morebut we all agreed on Japanese cuisine. We were seated in a cozy booth and our server took our drink orders. Pop music from the 90s/2000s blasted from the speakers but it created a fun ambiance! We ordered hot sake, Sapporo beer, chicken karaage, gyoza, yellowtail carpaccio, a chicken teriyaki bento box, tonkatsu ramen, and two different rolls (Baja and Bomb Diggity). Everything came out paced well and our server was awesome. We never went without and we were checked on plenty of times. Food was fantastic - the yellowtail tasted so fresh and the sushi rolls were "bomb diggity"!! Everyone enjoyed their meals and I wouldn't hesitate to return to try different items from their menu. There is literally something for everyone but the menu also isn't overwhelming. Parking was easy and plentiful on a Sunday afternoon. This was a 5-star meal for sure.

We ordered both the wagyu donburi and wagyu steak bites, and the meat was rich, tender, and literally melted in my mouth. The wagyu paired really well with the rice and each bite felt super indulgent. The Wagyu Sunshine was a nice contrast because the mango salsa added a refreshing citrusy brightness that helped balance the richness. We also ordered the Ginza sushi platter, which was beautifully presented with each nigiri coming on its own plate. The fish tasted fresh and buttery and made for a fun presentation. The chicken katsu was another solid dish -- crispy on the outside while still juicy inside. Also worth mentioning: they have a sushi roll deal where the second roll is 50% off, along with beer and sake specials which make it even better for groups. Overall, a great spot if you're craving sushi, wagyu, and izakaya-style food with plenty of options.

My appt was at 1:30pm and I got to Yashima around 1:40pm. I didn't realize they closed at 2pm but I needed my fix so went in anyway. Not one mention of the time and never rushed me for my order. I knew what I wanted already and ordered almost immediately, but didn't get my food until about 1:50pm. Everything was still cooked to order and tasted great (lunch special with salmon teriyaki, tempura and sushi + an extra order of tako). I eat pretty fast normally and finished right around 2pm. I asked for the check when the server was asking me if I wanted anything else and mentioned that I saw they closed at 2pm and wanted to get out of their way. She was very appreciative but never once made me feel rushed or like I stayed too long. Anyway, I really appreciate the extra level of service and professionalism. Pro tip: they have their own website for ordering takeout and delivery. Will have to try that soon.

July 1st/ 2026 6:02 PM…read more7:30 PM the singer started singing " horrible" Met friends for dinner. Our first time here. We parked in front. Plenty of Parking behind the restaurant too. Opened the dark door, very underwhelming! Small, stark white walls. No one to welcome you, our friend waved at us, so we proceeded to the table. Our waitress stood at the end of the table. We mentioned it was our first time and may we have sometime to look over the menu ? Ok and she left, she came back 30 seconds later, are you ready to order? NO the menu is huge and we need about 5 minutes please. One minute later she said OK what would you like to order ? My husband said, please can we have sometime to look over the menu I do not know yet. The waitress STOOD there staring at us waiting for us to decide what we want. My husband is on page 2 of the menu it is just so big you can't read it all in 30 seconds or one minute.! she wouldn't leave our friend. Finally looked at her and said just a few more minutes please and she just left.. she comes back and we asked for two separate checks before we ordered. I asked for my soup to go to the daughter and it came to me anyway I just gave it to the daughter instead.. the table area where I was sitting at was so sticky and dirty. It was gross one napkin and chopsticks. Never asked if we wanted more napkins or a fork or knife or anything else once we ordered, and our food was brought to us you never heard or seen her at our table again until we asked for our check & to go boxes as she was visiting customers at the sushi bar and very attentive to them. NOT a great first Impression.! When everyone was finished with their meal and needed two takeout boxes, we asked her for them she said OK but she really was interested in the people sitting at the sushi bar and hugged on them and talked to them and we never got our takeout boxes so then we waited 20 minutes 25 minutes comes and my husband gets up and goes to the owner and says can we have two takeout boxes please? Oh yeah sure so we get them we box up our food we asked for our checks. Another 20 minutes goes by. No check after waiting 30 minutes again we get up and ask for the check, you stand there and stare at us waiting to take our order but we never see you again once our food comes and you never finish what you're doing before you go to the next table if you can't multitask then don't do it please. When the food came, I was shocked at the size the tuna rolls they were so tiny. A snail is bigger. I was un impressed with the food. Nothing had any flavor to it. No salt wasabi that was on my plate was so small it was the size of a dime!!!!! and we love our wasabi! What a joke! The restaurant is so tiny and so loud and then they had a singer to celebrate their restaurant anniversary there which was beyond loud. Tables weren't full, but yet people were standing and waiting to be seated. That made no sense.. I am not a fan of TV's on the wall's at a restaurant. Sports bar's OK but not at a restaurant specifically when there is NO Sound. If you are a local and you come to this restaurant often, then the female waitress will love you! If you're new to the restaurant, she'll stare at you and until you order food and then ignore you once your food is handed to you. We will Never be back? Never ever again you couldn't pay me to come back to this restaurant ..! Do I recommend this restaurant in Covina absolutely not no way know how not even if it was free.!!!!! What was good about our experience, the beer, the company and the fact that we left.! Yay.!!!! FYI: my to box is in the trashcan. Once the drink and appetizer order is taken, Please do not approach a table until the menus are set down. Please clean your menu's and tables. First impressions are everything and our experience here was horrific. !!!! Please read other reviews about our server and the quality of the food. I am clearly NOT the only one thinks the serve lacks customer service.! And agrees about the lack of flavor regarding the food. Go elsewhere.

The broth was rich, hearty, and packed with flavor. The noodles had a great texture, and having the spice on the side let me adjust the heat while keeping a bowl mild enough for my little one. It's a small restaurant where you order at a kiosk, making pickup quick and easy. If you're looking for a comforting, flavorful bowl of ramen, this place is definitely worth trying.

If you can handle spice, I loved the regular spice level, otherwisemild is there next level down and was perfect for my friends.

The pork was a little bitmore on the tougher side when compared to the chicken. But no matter which proteinyou go with, they were all delicious.  A curry plate also comes with soup and salad. Both wereserved right away and very delicious. Despite how small the salad bowl was,they really stuffed it with salad. The server is nice and parking can getpretty crazy if you come during a rush. This is a great spot for a curry fixand would highly recommend.
