Judging from all the mixed reviews on this place, I suspect that the differences in opinion stem from a difference in expectations. I have a taste for real good Japanese food, but having tried Ninkazu during a Late-Night All You Can Eat fest on a Friday night, well my expectation's weren't that high so I was pleasantly surprised by the quality of the food, but nothing could've prepared me for the ATROCIOUS service we received.
To recall, we made reservations for 4 people at 9:30 (when the Late-Night menu comes into effect), and apparently a million other people did too because upon our arrival the strangest sight occurred - a huge crowd of people were gathered around the host stand in front of an empty restaurant while the manager calmly and efficiently yelled out reservations while servers began seating people accordingly. This is a good way to neatly organize the flow of the restaurant but it had a HUGE backlash to it - everybody orders at once.
Ok, so we were seated pretty early on and were hungry as hell so we filled out our sheet and flagged a waitress right away. I was excited because I noticed we had gotten our order in before all the tables around us, so I was choked when the food slowly began to pour out but none of it was placed on our table. The table across from us put in their order probably 15minutes AFTER ours and their sunomono, teriyakis, tempuras.. the whole works, came out before our miso soup even arrived!! After 25mins of seeing waitresses walk up and down our aisle with piles of food I looked around and noticed that the ENTIRE restaurant which was once waiting like us was now eating - we were the only ones left without any food. My boyfriend actually got up to inquire about this to the manager and he replied that our table's order was at the very bottom of the list - how can that be so when we were clearly one of the first people seated and got our orders in before so many others!? They REALLY need to work on this, because my sister said, and I agree, the whole situation really spoiled our appetite.
Nonetheless, our food finally arrived and I was pretty impressed with the quality control, their menu is a lot more extensive than most AYCE joints but it comes out pretty solid. Their beef short ribs are fabulous and the dynamite roll was tasty but skip the udon, it's sub-par.
Anyway, with that said I'm a bit reluctant to give Ninkazu a second try, maybe I'll come back for the regular menu but that terrible AYCE experience was enough to steer me away for a long time.
