There is no reason to pay full price for sushi so I always go to the happy hour. Even for dinner or something, unless someone is truly set on going out for sushi I try for the discounted sushi.
I actually prefer Kabuki's sushi then RA, they are bigger pieces and better tasting in my opinion.
Recommendation: To anyone that wants a good deal for happy hour and is hungry during an awkward 4 o'clock lunch when your class gets out.
