Disney food tends to be overpriced, with few vegan or even veggie options, and of mediocre quality. This was really very good, bordering on great, quality food and it was refreshing to have a good selection of supposedly vegan options on the menu, and a helpful server suggesting that the chef could make other veggie sushi was well.
My only complaint is that they listed their "vegetarian roll" as being with ponzu sauce, which ordinarily contains fish as a minor ingredient. I asked about it and was told that it doesn't have fish, but I didn't trust that, because it was "no, ponzu is just citrus" rather than "we make our own special vegan version of ponzu." I didn't argue very hard, but just ordered something else.
I wouldn't go out of my way to find this place, but if you are stuck in the area looking for food, I would check it out.
