This is definitely a place for cheap good eats in Vegas. They are open late (until 4AM).
They do accept reservations, but if you're walking in as a couple they will most-likely seat you at the bar if it's busy.
This place definitely gives you the Japanese restaurant authentic feel, and well, it is. The menu is filled with Japanese food items even delicacies (for example octopus and wasabi which is a raw slimy dish of octopus legs + wasabi) They have the regular menu and they also have additional items written up on paper with pictures of the items and these are posted against the wall.
It's soo hard to choose something from the wall because THEY ALL LOOK SO GOOD!! (amirite frequent flyers?)
I recommend getting the tuna tar tar. You get about 6 pieces of fresh raw tuna and some seasoning with avocado on flaky little squares of heaven.
It's delicious.
I normally get the mackerel fish here (they give you the whole fish) for only $4.95.
and the deep friend ika rings - squid rings like calamari but much better quality and thicker pieces. They give you a side of the oyster sauce which makes a much better pair than regular red calamari sauce. Seriously, you should try it :)
I recommend this place for a casual dinner or late night snack + drinks.
