Sushi 21 is my go-to AYCE Sushi restaurant for lunch...Their popcorn lobster is their signature dish and it's amazing.. They also have 2 unique cucumber wrapped rolls, Johnny and Naruto that are delicious. (Though, I do prefer Johnny).. Also, the garlic tuna and shrimp tempura are some of the best I've had in Las Vegas.. All-in-all, I highly recommend Sushi 21..
