I want to know why New Yorkers like 'Yama' Sushi so much, I personally don't like this place at all. If you ask any Japanese, good sushi are not big, huge, and oversized sushi, but it has to be delicate, fresh, and very tiny, assuming price is not a concern here.
I was amazed the popularity of this place, it's like a zoo on the weekends. Amazing how New Yorkers think they know how to rate sushi, but they actually don't, and I can't believe Zagat says this place is one of the best sushi restaurants in Manhattan.
Another thing, Sushi is eaten with your hands, not chopsticks.
