I had the Ruby Roll and Hot Soba. The roll was fantastic--would order again in a heartbeat. The soba was in a miso broth and was perfect for a cool evening. Service was quick and friendly. The menu was a little overwhelming, but only because they have so many creative options. If I lived here, I would definitely come again!

This restaurant is fantastic, fish is fresh and chefs are very creative. We have never been disappointed. We love the infusion roll with jalepino and the Zach rolls. Fresh sashimi can't be beat. It's a really small restaurant, make reservations or go early.

We've been here quite a few times since moving from Alameda to Castro Valley. At first, we missed the sushi in Alameda, but once we found i Sushi, there was no going back. They have traditional sushi as well as several pages of specialty rolls. My wife loves the large selection of vegetable rolls. Its on the pricey side, especially... More

I tried this place for dinner tonight. My son had the salmon with california rolls and I had the teriyaki tofu. My son didn't care for the california rolls. There wasn't a lot of crab in the roll and it was clear it was imitation crab. Our dinners were OK. Granted we didn't give the sushi a real try.

Is this place pricy? Yes...is it worth it? YES! Come here knowing that they will serve you unique dishes, extraordinary sushi and incredibly fresh seafood and even kobe beef! The raw scallops are absolutely amazing! They melt in your mouth like butter, and they're what I love the most so far.

I've been to I Sushi a number of times because friends like to come here when they come to Castro Valley. They have the standard special rolls along with some very unique combinations that include fruit like mango and various other combinations you wouldn't normally experience. However, they are WAY too expensive. Yes the fish is fresh, yes some of... More

How lucky for us that I live a mile away from my favorite sushi restaurant. I Sushi occupies a normal 2-level restaurant site inside the Castro Valley Village, the heart of our suburban town. Their menu is amazingly detailed and always evolving. They offer 50+ sushi rolls at all times as well as delicious sashimi, three kinds of oysters, always... More

We stumbled across I Sushi while visiting friends in Castro Valley. The menu was huge and somewhat overwhelming. I didn't even know where to being. Luckily, the server was great and I was able to tell her what I liked and she recommended great options or just created something. It was a little pricey but to be expected for the... More
