Only one night (Sunday 5/30) in Portland--my first visit--and I'm in a quandary about where to go for dinner. I've culled at least 8 possibilities from these message boards. My wife is unfortunately allergic to shellfish, but I'm not, so place must satisfy both desires. At least for this night, cost is not a consideration. I'm also partial, having lived in Italy for 18 months, to excellent (northern?)Italian food. Suggestions?
