Alright guys. I've eaten here at least three hundred times, so I know what's down. Firstly, the food is very good. sashimi is spot on, although on busy days you can taste (for example the salmon) is a bit more hard (crunchy) than usual. This is why i recommend going for all you can eat or eating during the regular dinner times on weekdays. AYCE on a weekend = terrible service + long wait times + weird ass food quality sometimes.
In terms of the quality, it's definitely a solid 3/5. Sometimes it gets the 4/5 rating when either 1) the oyster motoyaki is actually hot (always warm for some damn reason) 2) the chicken/beef teriyaki is oversaturated with sauce making it soggy and warm or 3) the sunomono's noodles are stiff (prepared and left out for too long)
Otherwise, the dynamite rolls, alaskan rolls and the chopped scallop cone definitely are the show stoppers. These ones are good EVERY time. Don't get me started with the chopped scallop cone, that thing is bang on. Notice how if you eat it in an ice cream format from top to bottom, you can still taste chopped scallop at the bottom, they don't cheapen out on this stuff. Secondly, the rolls are adequately sized and they've got down the formula. Why i'm saying this is cause sometimes i eat at bonzai and it's as if they didn't even bother cutting the pieces of seafood from the whale and they served it to you as a whole. The portions are too big! ninkazus got it right.
Service is a bit hit or miss depending on the number of people eating. There is this one asian girl that used to owrk there and she was really nice and awesome. Don't know where she went.
Ambiance = typical japanese restaurant, surprisingly spacious allowing for all the sumos and heavy eaters to spread their legs and unbuckle their belts
The last thing i'd like to mention is to never order too much here or too little. They love to downsize your 20 sashimis to 12. So what you shoudl do is never order anything over 15. Stay within the 9.8789 to 15.000 number range for each type of food and you won't get cheapened out on.
The price is super good. All in all, if ninkazu was open 24/7, I'd bring a sleeping bag there, nuff said.
