    This place has such good clam chowder in the bread bowl!!! I used to go to their SF location when I lived in the Mission. The sourdough tastes fresh and the clam chowder is really nice. My boyfriend doesn't even like seafood (picky eater, not from California) but he liked the clam chowder, too! I also love the Philly rolls. That smoked salmon makes me so happy . I don't ever want to get Philly rolls anywhere else! When I'm able to eat spicy food again (reflux) I can't wait to have the spicy tuna. That used to be a favorite of mine. It's nice to eat at high quality family owned places like this.

    Solid restaurant. More takeout than dine-in. Everything served as to-go but they do have seats. Small, so it can get crowded. Extensive menu for sushi etc. Food was solid. Nothing spectacular, but all very decent. The spicy salmon poke did taste a bit off, but might have been just me. Fried fish was really good and I usually don’t like the corn meal breading. Sushi was just ok. Their fish looks fresh and appetizing. I don’t think I’ll come here on the regular, but I definitely will consider it an option!

    Location is really nice then Castro valley. The staff was amazing and very professional. Food came out real fast. And so many options. The only issue I did not get five stars was due to the rice. One of the meals it comes with white rice. Sadly the white rice was chewy and hard. So I had to throw it away when I got home and make fresh rice. So definitely check your rice before you leave.

    This place popped up on social media and heard that they serve fresh seafood. So I decided to come here. This place seems to be one of those restaurants where you go for lunch and have it to go. Many people were seated on the tables not to really dine in, but to wait for their orders. It serves all sorts of seafood: sushi, burgers, fried seafood, poke, etc. I heard that their main location is at SF, but they recently opened their other location in Castro Valley. Normally when you go out to eat poke, you choose your base, protein, sauces, and other toppings. This one is different because poke is served in a tray with a side of rice and seaweed. I heard that they’re out of spicy salmon poke, but there’s some in the display glass. However, I think we’re told that they need to chill them first before serving them. Prices are fairly cheap. It’s like going to fast food, but fresher.

    Fresh, high-quality seafood! The sashimi and poke were super fresh, and the flavors were spot on. Service was quick and friendly, and the prices are very reasonable. Great local gem in Castro Valley.

    Perfect for grab and go. Poke are super cheap and delicious. They also have rolls if you want to wait for it. There’s tables, seats, bathrooms, and plenty of parking.

    I ordered the salmon bowl and it was so delicious! You can tell it was high quality fish. Sauce was good. It felt balanced and exactly what I was craving. Affordable delicious food in Castro Valley. I will be back!

    Saw that they have poke and needed to give it a shot. They actually have a decent amount of other seafood here. Cool mom and pop kinda restaurant. Ordered the ahi and spicy salmon poke. If you’re mentally thinking of Hawaii poke, it’s not the same. But if you’re good with a shoyu ahi and spicy mayo salmon on fresh rice? It’s solid. Definitely hits a spot for some poke. Worth a stop by
