I used to live in Las Vegas, and during that time I used to frequent RA. As a visitor, I dine in once in a while. However, I can't really say it's as good as it used to be.
Rolls were good. Favorites were the spicy crispy tuna and the viva las Vegas roll.
I came to RA a day before my birthday, and luckily they still gave me a complimentary dessert: deep fried tempura ice cream. It was a huge portion enough to share with 4 people.
The cocktails are delicious. Snake bite was yummy. I'd definitely recommend this sweet, strong drink.
Waitresses were awesome, attentive and friendly - that's a plus.
Location was convenient - The Fashion Show Mall!
Ambiance is black, red and dark. Very normal of hip Japanese trendy spots.
