Convention center area - good, casual restaurant recommendations needed
My brother will be visiting Portland for a week starting this Sunday. He will be staying at a hotel a few minutes from the Convention Center and would really appreciate casual restaurant/food truck/fast food suggestions within a 15-20 minute walk of the Convention Center. He likes pretty much all cuisines, but doesn't like formal, stuffy places much. Also, he would like to avoid chains and try local specialties, if at all possible. Thank you for your help.
