On a hunch, I went to Nihonhashi Zen without checking Urbanspoon. I wish I did check because it's like rate of 44% was very accurate. The decore resembled a cheap Japanese Restaurant but the prices on the menu would rival of michelin hat restaurants. I ordered some Sashimi which had 12 pieces of Salmon, King Fish and Tuna for $40.
The Sashimi was fresh but I was turned off by the cheap decore and when I saw food on the other tables, I was not willing to order any more for the michelin prices. I'd avoid this place if I was you :P
Prices: If you had a proper meal it would probably be $120-$150 per person
