We were really excited when we arrived, but there was already a long line at 5:00 PM. Luckily, we were seated after about 40 minutes, which honestly wasn’t too bad. We were seated in the extended area, which felt more like sitting along a walkway—not the nicest seating experience.
We opted for the signature menu option. Some items were limited to one per person, including salmon, hamachi, tuna, albacore carpaccio, ikura, bluefin tuna, and jumbo scallop.
Unfortunately, the food quality was disappointing overall. The “jumbo” scallop ended up being only half a scallop per person. The albacore was very dry with a rubbery texture.
We also ordered several hot dishes, but none of them arrived hot, which is pretty basic for an AYCE spot. The ramen came in cute small bowls—nice for sampling different flavors—but nothing stood out. The agedashi tofu was especially disappointing: cold on the inside, with only a few drops of sauce drizzled on top instead of being served in a proper sauce bowl. The soft-shell crab roll was another miss—the crab was still icy and had a strong frozen taste.
On the positive side, the salmon, yellowtail, and tuna were pretty good, and the service was excellent.
Overall, while the service was great, the food quality and seating didn’t live up to the hype or the long wait.

Came here with my friends and had such a good time. The all-you-can-eat is 100% worth it. We got the signature and tried pretty much everything — all super yummy.
The fish was really fresh and the quality was honestly impressive for AYCE. Staff were friendly and attentive, and the place itself was nice and clean.
Great vibes, great food, and definitely a spot I’d come back to.

We came here to celebrate a family member’s birthday before heading to an improv show nearby. The interior is nice — clean, open, and modern — and service was relatively quick, which made it a convenient pre-show dinner spot.
Unfortunately, the food quality was inconsistent, and some dishes were genuinely disappointing. The biggest issue was the fish carpaccio. The tuna was chewy, unnaturally bright red, and topped with pico de gallo, which felt like an odd and unsettling combination. It was honestly one of the most uncomfortable dishes I’ve had at a sushi restaurant.
The nigiri was acceptable but nothing memorable — fine at best, and not something I would go out of my way for. Overall, the experience reinforced a growing feeling I’ve had about all-you-can-eat sushi spots: they often prioritize volume and perceived value over fish quality and proper preparation.
Food: 2.5/5
Service: 4/5 – Quick and attentive
Ambiance: 4/5 – Clean, open, and modern
Overall, I’m giving X-Fish a 3 out of 5. While the space and service were solid, the fish quality — especially the carpaccio — really missed the mark. I probably won’t be back, and this experience confirmed that I’d rather spend my money at restaurants that specialize in sushi rather than AYCE concepts focused on quantity over quality.

The servers were friendly, but the host/manager was rude. The omakase tasted good, though the premium sushi is not all-you-can-eat. I would have given this place 4 stars if not for the host/manager. We waited 45 minutes on a night when the restaurant was only about 70% full. Several parties who arrived after us were seated first. When I asked the manager why, he said it was because they were parties of four, which didn’t make sense since there were at least seven empty four-top tables available. Ironically, after all the other four-person parties were seated, we were finally placed at a four-top table as well—30 minutes later.

It was my first time at X fish izakaya and it certainly won’t be my last. Our server Daniel answered a lot of our questions. During lunch they have an AYCE special for $29 or you can upgrade to the Omokase level at $55. I definitely think it’s worth it. You get an order of the chefs finest cuts of sushi and a lot more to choose from. The service was fast and friendly. You order the nigiri sushi using the paper order sheet. The rolls, hot food, and drinks are ordered through your phone with the QR code they give you. The black garlic ramen was awesome. We also picked up the garlic albacore roll and the X fish specialty roll. Free parking is available just steps away from the restaurant. It’s got some beautiful decor and plenty of open space for big parties. Overall great experience and can’t wait to go back! Reservations are highly recommended.

Minimalist all you can eat sushi restaurant, that is near the heart of downtown Brea.
The nigiri selection is decent with little rice under the pieces of fish. The rolls are pretty tasty, but go for the specialty rolls instead of the basic ones.
There is a 90 minute time limit, and service is slow, so best to put in a big order in the beginning for the nigiri and then get the kitchen dishes and rolls after if still hungry.
The line up is crazy long so best put yourself on the yelp waitlist before heading down.

I met my friend here for lunch and we wanted to try the premium items which is the all you can eat Omakase at $55. She introduced me to the yellow tail collar and it’s so delicious, I can’t believe I never tried this. I also recommend the Agedashi tofu , shishito peppers, calamari, but most of all the chef choice plate was fantastic and beautifully displayed. I love how fresh it is. I only wish I had more of the “hon maguro”! Such a satisfying meal.

We visited on a Wednesday afternoon for lunch and were seated right away. The restaurant was pretty crowded. Our waiter explained how the menu works for each tier. We decided on the $55 omakase which includes the premium AYCE menu and 9 specialty fish. Every piece we ordered tasted super fresh and paired so nicely with the fresh wasabi. My favorite was the yellowtail collar and garlic edamame. We also ordered a black tonkatsu ramen and the broth was delicious and flavorful. We were stuffed and definitely over ordered. So make sure to bring your appetite!

Came here for AYCE sushi and this place did not disappoint!
My friend and I tried the signature menu. We ate a lot and everything was delicious. Everything we got are in the pics minus 2 food pics. We can’t wait to go back when we are in the area.
Customer service was great. The staff work quickly.
Free parking in the parking structure.

My first thought was, this place is going to be EXPENSIVE. But I was pleasantly surprised to find that it was priced fairly and that it was all you can eat. I normally don’t like all you can eat sushi but this place was great. My kid actually tried new fish and other rolls and liked them. The atmosphere was great, very nice for its price point. I’ll definitely be back.
