LOUD. Loud, loud, loud.
That's seriously the only thing I can think of when anyone suggests Ra. The music is blasting so loud that you have to yell across the table to your companion - definitely not a pleasant dining experience. - 2 stars.
The girls (yeah, I've NEVER had a male waiter or host here) are pleasant enough but service is a bit slow. - 1 star.
On the other hand, the food is good and really reasonably priced - I recall Happy Hour being around $18 for a couple iced teas, Vegas Rolls, and a few other rolls, having some left to take home even. Otherwise, it was $36 for dinner the last time I went.
So, as a compromise the last time Ra was suggested, I dragged my oh-so-tolerant date to the Ahwatukee location. It was MUCH QUIETER and the service was surprisingly good, despite it being 10 pm on a Saturday with a packed bar. It was worth the 5 miles to Ray and I-10, because the sushi is definitely good.
