We have more than in picts, but can’t take since taking care a 3yo at that time. Even my daughter love some of the couses😉🥰.“

“O.M.G. i stumbled on this place randomly aince the place we wanted closed. Cook your own food like Kbbq. But its not all you can eat. Proces are a bit high. But the quality of food is AMAZING. Literally melts in your mouth. Real Japanese taste and items. Before this place I had no idea wasabi actually had flavor wasnt just spicy.Even the rice is better than normal. Worth the price but get ready to spend about 100 to 150 for 1 to 2 people. Again... delicious. They dont have many decorations and the tables are a lil cramped for tall pepple. I cant think of any music playing. But the people are very nice and attentive.“

“The best ramen you will ever eat anywhere. Great service. Great prices. Worth the wait.“

“So good and server are very friendly“

“So happy they finally opened! Always great service! Amazing quality meat and fresh veggies!“

“There is a sublime, almost religious satisfaction in sitting down in front of a live fire with a plate of raw, heavily marbled beef and a freezing cold beer. It’s an interactive theater of fat, smoke, and instinct. And if you want to experience this ritual at its absolute peak, you don't look for white tablecloths or corporate steakhouse polish. You look for a place that feels a bit tucked away, cozy, and smells instantly like caramelized soy, rendered fat, and sweet wood charcoal the second you open the door.

This is world-class Yakiniku.

You start with the yukke—the raw beef tartare. In lesser hands, raw beef can be a texture game with no payoff. Here? It’s seasoned with precision, rich, clean, and spiked with an egg yolk that ties the whole beautiful mess together. It’s a declaration of intent: we know meat, and we know how to treat it.

Then, the main event. Plates of A5 Wagyu, Kobe outside skirt, and prime beef tongue arrive, sliced with the kind of geometric reverence usually reserved for fine tailoring. The marbling on the Wagyu doesn't even look real; it looks like a geological map of some frozen, beautiful landscape.

You drop a piece onto the grill. It hisses. The fat hits the element, flares up, and perfumes the air. You don't leave it on long—just enough to get a quick sear, a bit of char, while keeping the inside beautifully rare. You dip it in the tare, put it in your mouth, and it simply ceases to exist as a solid. It melts. It’s an absolute explosion of umami that makes you want to close your eyes and laugh out loud at how absurdly good it is.

Even the sides here aren't an afterthought. The kimchi fried rice has that deep, fermented funk and spicy kick that cuts right through the luxurious weight of the beef, waking up your palate just in time for the next round of short rib.

It’s not a cheap night out, and it shouldn't be. This is a celebration of the animal, handled by people who deeply respect the craft, served in an atmosphere that strips away all the pretentious nonsense of high-end dining and leaves you with what matters: incredible food, good company, and the smoke in your hair. It is, quite simply, perfection.“

“The best ramen you will ever eat anywhere. Great service. Great prices. Worth the wait.“

“Hi guys I went to the sushi place, I haven't eaten sushi for many years I I decided to try a sea food soup, that was so delicious my daughter and me went to the beach there we enjoyed our food she likes, sushi, we spend the rest of the day on the beach,that restaurant the food is very good.“

“Everything was excellent! Service was top notch as well.“

“Sushi Koto is always a treat for me. I love to come here for what I feel is the next best thing to eating in Japan. There is always a wait for Sunday brunch, but they do take reservations. Excellent service and friendly staff. This is definitely not your ordinary neighborhood Japanese restaurant. Highly recommend it!“

“We were a party of 5 with two babies and we couldn’t have asked for a better experience. The food was excellent, super friendly and attentive. My absolute favorite was the takoyaki, it’s probably some of the best I’ve ever had. We ordered the Bento box for the kiddos, and 5 other rolls, all equally as delicious. The decor is super cute and cozy, ideal for a date night as well as a family meal. I can’t wait to go back.“

“My friends and I tried this place for the first time and everything was SO delicious! We started with the cesar salad, and it was one of the best I've ever had.
We tried the branzino, and we loved the lemony sauce that complemented both the fish and side of brocolini!
The pork jowl dish was so tender and packed full of flavor, and it came with lettuce that made each bite refreshing.
We also got the miso carbonara which was creamy, perfectly seasoned yet not too heavy.
Service was very nice and fast, so overall we had an amazing dinner!“

“Tasty food and nice place and very good price 😋“
