Raw fish and accordingly sushi then as well is something for what I've always said Thank you, but no, thank you!
But reading you talking about it and watching those photos you've posted here, I think at such place as apparently this Obi Restaurant is, I might reconsider that possibility and give it a try. 🙂
Oh you must! When it's done right, it's sooo good.
I would say that if you can have a rare steak, or a carpaccio, you'll be just fine.
Don't forget, it's not old poopoo fish. It's fresh, the best cuts, made by trained professionals
