Visited three times now and it’s become a reliable choice for Japanese food in Cardiff Bay, especially for group dining at the Red Dragon Centre.
The concept is simple and works well: you get up to 2 hours to eat, and you can order a maximum of 4 items per round from anywhere on the menu. Orders are placed by scanning a QR code that takes you to their online ordering system, though paper menus are available if you prefer — a nice touch.
At weekends there’s also a small buffet, which adds extra value and variety compared to à la carte dining. Fair warning though — it fills you up fast. We managed about 1 hour 15 minutes before tapping out. Amateur eating on our part
This place really shines for large parties. Pro tip: try to get the table to order the same items (for example, everyone going in on Dragon Rolls). When you do, they often serve it as one huge shared platter rather than individual dishes, which is far more fun and sociable.
Service has been consistently warm and friendly on every visit — there’s always a smile from the staff, and the atmosphere feels relaxed rather than rushed, despite the time limit.
Overall, a solid and enjoyable Japanese restaurant in Cardiff Bay, ideal if you’re heading to the Odeon cinema or bowling at the Red Dragon Centre and want variety, value, and a sociable dining experience.

The food was lovely, the service was quick, and the taste of the food was fresh and tasty. I love it and look forward to revisiting it. The atmosphere could be better and more refreshing.

Have eaten at Vulcano twice, both times doing the 50% discount a la carte prices. We did this because some of the dishes we wanted to try (especially the Spider Maki) were not available on the all you can eat.
The prices are expensive before the discount, but felt about right after the 50%.
I enjoyed the food for the most part but have found it hit and miss. I ordered the same thing both times I visited and the first time was excellent, and the second time very disappointing.
As you can see from the pictures, the food was absolutely slathered in sweet sauces, and these had pooled on the maki because it was stacked flat like a pyramid. We couldn’t really taste anything but the sauces and these quickly became very rich and sickly.
The portions are excellent though, we definitely didn’t leave hungry! And the staff are lovely too! Absolutely excellent service!
I’m not sure we would go back after our second visit. Shame because the first time was delicious.
The food is visually stunning though! Definitely worth a try at least once!

I came here in Jan 2026, I’ll be as honest as I can from my experience here.
Drinks are good and the food is really good. The menu itself is really big….lots to choose from!
You have 2 hrs to eat at much as you can for £35, only thing I didn’t like was you can only order 4 items per person at a time and it’s all done via a QR code when you order.
I recommend you get the train here and arrive 15 minutes before a booking, that’s if you made one! You can do it via thier website if need be. I recommend doing that.
I will be coming back here,
Thank you!

We ate at Volcano with the all you can eat menu, you can order 4 items per round and they had no limit on the rounds.
The hosomaki was delicious and good quality fish.
Hot food was pretty good too.
The “sashimi salad” was one thing that actively was quite bad, it was some salmon and salad but drenched in this sriracha mayo/fish sauce that i actually had to pour out in order to eat it.
Overall, it was a nice time, but some qualms I have is the sashimi being limited to only two orders per person, meaning you can get a maximum of 6 slices of sashimi the whole time, i’ve been to sushi buffets with this same concept outside of cardiff and others do include sashimi for a lesser price point, as well as this the rice to fish ratio on a-lot of the sushi dishes is a little bit cheeky, plus most rolls in the futomaki dishes include crabstick for some reason (probably because its a more cheaper item)

Amazing! Beautiful restaurant with friendly, attentive staff and excellent food. Clever take on an ‘all you can eat’ where you order what you would like (4 items at a time every 15mins) and it is bought out to you as soon as it’s cooked. This means it’s super fresh and hot when it arrives, not to mention beautifully presented…looks exactly the same as the pictures. Will definitely be going again and would highly recommend, thanks to all at Volcano!

Went on a Monday night so was relatively quiet. Had the all you can eat option, food was served swiftly and was hot and fresh. Service was friendly and efficient. Food was genuinely tasty and well made. In particular, the shrimp tempura, lamb chops and beef skewers stood out. Sushi was delicious and fresh. Asked for Wasabi and Gari that was brought to our table. Great atmosphere and an overall positive experience. Impressed visitors coming to the area.

Amazing service. They had set price menu for about £34 you could order anything unlimited for 2 hours. They had regular menu too. We ordered 3 rounds and I was so full. The quality of the food was very good. Their in house wine was good quality one too. I recommend it.

Amazing food, excellent service, great value for money. Yes the all you can eat is limited but four dishes ordered five times is an enormous amount of food. We had to stop at the fourth…! All freshly prepped. Really tasty. Would definitely go back. Staff are amazing too.
