RA sushi is amazing, sadly only in Chicago. I have yet to find one here that surpasses my expectations. Happy Hour is the best time to go and the portions are very generous. I probably ate there at least five times over the span of two weeks that I was visiting. I've gone days on end craving their pineapple cheese wontons, "RA"ckin' shrimp, and tootsy maki (with cream cheese).
