I go to Vegas a couple times a year and my parents love to go here. I was a little surprised by the reviews and thought I would give my opinion.
Makino's is a fun place to go and they always have a good selection of food and it is well stocked. The food just doesnt sit around for a long time so it is fresh. I LIKE the sushi there. They use good ingredients and they also vary the combos. If you do not see what you are craving you can ask the sushi chef to make you a Hand Roll.
The Tempura is a highlight for me. I would get the udon but that is a little too much food for me. :) Maybe it is the economy but I have noticed some things disapearing like the creme brulee. But all in all, we have never left the place hungry.
The only suggestion I have is offering a small Senior Citizen discount. If you get the free coupon book, you can get a free beverage.
