I'll be in Portland for the first time in April for a conference, staying in Jantzen Beach. No rental car, so I'm looking for cheap (less than $20) places to eat within walking distance of the hotel. So far, all I've found close by are the hotel/mall restaurants (Shenanigan's and Stanford's) and big fast food chains. I'm looking for casual places with to-go menus for lunches or places that wouldn't be awkward to eat at alone for dinner. Delis, cafes, soup/sandwich places a plus. Thanks in advance for the help!
