RA is a very popular sushi restaurant and has a high customer base. The atmosphere is very trendy and fun.
This restaurant is more like a bar and a cool place to have drinks and get together with friends. Unfortunately it is not a very good place to get quality sushi.
The rolls and cuts are small and don't have the quality that some of the more dedicated sushi joints do. Also for what you get the prices are too high.
Fortunately the service is usually pretty good because of it's "chain-based" origin and are usually nice.
Also, I like the fact they have a nice patio area for those who want to eat outside and enjoy the weather. The patio still receives good service generally.
Overall I would recommend this place for a fun outing with your friends, but not for a night of good sushi.
