Before I went to Portland I had never heard of a "food cart" before. I quickly learned that it's one of the biggest tourist attractions! All over the downtown area you can find clusters of food carts with options available for all diets (including paleo and vegan!). I loved the variety, and the only bummer was that the food carts we went to on Friday night had closed at 5 p.m. So be sure to get there during the normal business hours!
