Nobu at Ceasars is a must go everytime I am in Vegas.
Warning: Sushi and Sashimi is so good, eating here will make it difficult to enjoy similar dishes anywhere else.
I have made reservations and ate in the main dining room, however I prefer sitting at the sushi counter which is usually available by Walk in.
Best Rolls we have had are when we keep an open mind and ask the sushi chef to prepare his favorite.
I crave the Yellowtail Sashimi with Jalepeno. They drizzle a citrus sauce on it that is to-die-for.
If you can sit on the far end of the sushi counter from the entrance, you may get the added entertainment of watching the Hibachi Chefs prepare at the private party Hibachi tables.
Good selection of unique cocktails, my favorite is the Lychee Martini.
I live in Seattle which has good sushi options but the best Sushi/Sashimi I have ever had is at Nobu. And the the fun and beautiful environment makes it a special experience. I have been to Nobu at Ceasars 4 times in the past year and never been disappointed.
