This location is my favorite - and not necessarily for the food, but for the atmosphere. Of all the Ra's I've been to in the Valley, this place has the nicest servers.
Now, as a California native, I've had not just good, but great sushi - and although Ra isn't up there, it's pretty darn decent for Arizona. Reverse happy hour is the best time to go because you can get a lot for a little. The only complaint I have about Ra in general is that you're not allowed to do tradtional sake bombs - you know, with the chopsticks - yet other Japanese restaurants let you. Oh well, can't win 'em all!
