Oishii does have a nice food menu, but it doesn't make up for the lack of seating, the not-so-nice wait staff, the long wait and the hurried atmosphere. None of this is even close to how the Japanese dining experience is meant to be.
To me, enjoying a meal isn't just about good sushi. It's about presentation, atmosphere and being a guest. Dining at Oishii lacks all three in my book. I have no problem spending large amounts of money on a great dining experience, especially when they earn it by making my meal so enjoyable, I want to tip 30%.
I'm a sushi snob, not just for the nigiri or the maki, but for the total taco(pun intended).
One other thing that is crucial to the Japanese dining experience is a good sake menu, which Oishii does not have.
I would only recommend this place for take out.
