We've been to RA Sushi in Vegas and California.  They have great sushi and other nice dishes.  It's a fun place to hang out and have dinner.  If you want some help ordering, go for the guest faves!  They even make yummy green beans and we also like the degaku tofu. I like the cucumber \"kimchee\".  It's not like real Korean kimchee but if you like cucumbers it's a nice refreshing side dish.  My family loves the chicken wings and the tacos in addition to their sushi and rolls.
