I vote for Ra Sushi, for a couple of reason... 1) The atmosphere is great, meaning they it has good ambiance, music is good, and the wait staff is usually great. 2) The food is great as well. I've been to quite a few sushi places around the Galleria area and Ra is definitely great. If you want some good sushi, try their speciality rolls like the Viva Las Vegas Rolls. Good luck on finding a place!
