Ra Sushi has very little for vegans except the most basic kind of avocado or cucumber sushi rolls (or, as I like to say, the Japanese equivalent of iceberg lettuce salads at steakhouses). The bar area is pretty nice, though, and I like the decor. Be warned that their mixed drinks are pretty strong and not particularly well-mixed, in my opinion. The service was friendly.
If you happen to be in the area, this might be a good place for a late-night drink, as all the other bars in the neighborhood seem to be wood-paneled Irish pubs.
