The best restaurants serving Japanese food in Cardiff South Wales

Highly recommended :) Delicious Japanese food and drinks, friendly service, affordable prices, clean and cosy setting. Good range of fresh seafood and vegetarian/vegan options. Only wish they’d include a few veggies in their rice boxes too. Booking in advance is advised as it’s a small restaurant - easy to do via WhatsApp.

Amazing little sushi place. Our server was so funny and super helpful. Food arrived quickly and tasted amazing! Atmosphere was warm and welcoming and plan to return again soon.

We were so happy to have finally visited here. We first heard of the restaurant because of Uncle Roger and have been ordering the meal kits as a result. The food in the restaurant didn't disappoint. The meals arrived pretty quickly and were delicious. Can't wait to go back again when we're next in Cardiff.

So nice to have this lovely restaurant back open in Roath!

don’t know why some people gave this place a low rating (when we checked on google). my girlfriend and i got greeted very nicely and was immediately made aware that there was no rice available as their rice cooker had broke, and they offered various substitutions for this problem. there were only two servers and it was quite busy when we came in. the seating was comfortable and the atmosphere was very homely and relaxed. we didn’t have to wait long, 10 minutes at least which was plenty of time for us to get settled in and decide what to eat. i ordered the prawn katsu curry (forgetting that there was no rice available) and when i asked for it the server made me aware that there was no rice left, however, if i so wished, i could get the rice cooked with no promise that will be cooked thoroughly and that it might be a little/very crunchy. i happily accepted those terms as i am a fan of crunchy rice. my girlfriend ordered the tonkotsu ramen with pork. we got our food delivered within a reasonable amount of time and the portion sizes took us by complete surprise. they were a lot bigger than we expected, but they were perfect portions as after finishing i was neither too full to the point i was uncomfortable, nor was i still hungry for anything else. the prawn katsu curry was DELICIOUS!!! our server had warned us that the rice may not turn out good due to the rice cooker malfunctioning, however, the rice was perfect. my girlfriend adored the ramen as it was creamy and well prepared, it would melt in your mouth perfectly. unfortunately they didn’t have desert available, but that didn’t ruin the food that we had just eaten. once again the servers the extremely friendly and welcoming, giving us recommendations when we asked, apologising for any problems even though they didn’t have to, overall it was just amazing. highly recommend this place if you’re a fan of japanese food. will definitely be coming back here on my next trip to cardiff!

This is my new favourite restaurant. Cozy, unassuming, family run with a warm and welcoming atmosphere... and then the food arrives. There was silence at our table except for the occasional sigh as we enjoyed a taste sensation. I can only say you must pay Osaka in Cardiff a visit. You won't regret it.

Consistently shocking service. I feel like the person who works there has a future as a doctor's surgery receptionist, they do as much as possible to prevent you ordering. They try and get you to use a machine to order, which often doesn't work, and if you mention it you get scowled at. They seem unaware of how to fix it. They are extremely rude when you arrive and if you're lucky enough to get their attention they treat you as an inconvenience, manners don't exist. They are obviously focused on Deliveroo rather than walk ins for lunch. Sadly it's nice enough sushi (albeit a very confusing menu that makes no sense on the ordering machine) but the service is rude and confusing. This has happened on too many occasions now and I won't be returning.

Terrible service and attitude from the get go. When we arrived we asked how the menu worked as it was a first time to visit. Waiter rudely said you will have to wait until you are seated. We were seated after people who came after us. And their orders were taken well before us. We waited for the water to come to us and drink orders We placed some orders and received some food but had to call them over to ask when we will receive them and we’re basically told we just had to wait it takes time to prepare. So we ordered a few more items and waited. When we called them to ask they said it takes time to prepare and they will send them out when they were ready. Funny the people in the next table was getting theirs and seems when we called them back for our last order that we were waiting on seems they got our orders and sent them back. So no one figured out this out. And as they said we had to wait we would have to wait again the normal 15 mins to prepare. So we said we had waited long enough and we were going elsewhere to finish dinner. They did not offer to rush any other dishes or offer anything. And they even charged the tip lovely. Crappy service and they had enough balls to take a tip. No thanks Yo Sushi not visiting your Location again

Been here twice in the last fortnight, fantastic menu, fantastic food, great atmosphere. Very reasonably priced and the quality is excellent. If I had to find fault I would say that the CS Ramen was a little bland but the array of condiments sorted that out. Highly recommended
