My East Coast parents, both 70 and one in wheelchair, want to take my daughter and a friend to dinner somewhere within 15 mins of Reed this weekend. Looking for someplace accessible and not too cramped with an atmosphere that will appeal to both college students and older people (hip w/out being overly noisy). Daughter mostly vegetarian but eats some fish, everyone else omnivores. Parents' first time in Portland, so something they might not find in Boston area would be especially cool. Thanks!
