I think that Oyshi is one of the best AYCE sushi restaurants in Las Vegas.  It is a bit of a far drive from the strip and from where I live, but it's worth it.  The AYCE prices are $21 for lunch and $26 for dinner.  The AYCE not only includes various sushi rolls, but also includes various items such as steaks, mussels, sweet shrimp, some nagiri choices, and dessert.\n \nMy Top Picks for AYCE:\n-Ahi Poke\n-Kamikaze Roll\n-Tiger Roll\n-Rainbow Roll\n-Rib Eye Steak (comes out sizzling on a hot plate about 6-8 oz)\n-Mussels (2 comes in every order)\n-Vanilla Berry Parfait\n \nOyshi also has a normal non-sushi menu such as teriyaki chicken, egg rolls, and a beef bowl, if you ever have any non-sushi diners in your group.  The service there is decent, some servers are friendly some are not.  I've never had a problem with trying to get a table here.  My only qualms with Oyshi is that they tend to play rave/techno music there that does not match the ambiance.  And they also automatically add gratuity or parties of 6 or more, when it is usually customary to add gratuity for parties of 8-9 or more.
