Japanese buffet in Vegas started with Makino. The regular buffet where all dishes are out and you just pick what you like.
They charge $25 for dinner. The fish quality at Makino is not very good. For their sashimi, the fish cuts were of low grade and the color Of the tuna was very pale. Their rolls are all very saucy and the fish in it tends to be soggy too.
Their desserts are not bad though and the service was pretty good. That's where the 3 stars are for. They have a good selection of desserts.
A quick note, if you are celebrating a birthday at Makino, be sure to mention that when you arrive to your server as they will make a special cake for the celebrant.
