I hope we are talking of the same Oishi Reastaurant on De Soto.
Of all the Sushi restaurants, in all of the San Fernando Valley, in all the world, we walked into this one!
We arrived 8:30 PM. Hungry! They seated us. We'd had a beer while waiting and we looked over the menu, looked good. We ordered. There were almost no other people in the place. While we were waiting, the scent of Pinesol came wafting over to our table and almost rendered us violently nauseous! They told us they close at 9 PM. So, only, 15 minutes to go we waited, and waited. The Pinesol wafted! It was just too much! So, we said OK, we'll take it with us. We got home and opened the food. Supermarket quality was better! The Yellowtail was really yellow, like they'd kept it in water to keep it from drying out. Fresh? Forget it! The Unagi was out of a plastic container, not even the usual sweet sauce and sesame seeds. Dry! California roll, Vons sells fresher food. And the Tempura roll was completely tasteless!
I'd hope I would have a good Sushi place to go to, but this was a disaster! Never again. There wasn't a Japanese person in the place! Customer or staff.
My rating: 0 they couldn't pay me to eat their food again.
