We got our food at another food cart around the corner, which was out of several items. We passed Sonny Bowl and were in the mood for some fried tofu or something, and they had it. All we got was a little container of fried non-meat (see my photo - you'll want some!). It was REALLY good, and had we not already had other food, we would have gotten more at this food cart. The service was really good - nice and pleasant. I think it only cost $3 - which was fantastic.
I love all the food carts in Portland, and especially that there are so many vegetarian and vegan ones to choose from.
