The best food isn’t always in a fancy restaurant, so I always check Jane & Michael Stern’s Roadfood.com before traveling anywhere new. Their site gives you the skinny on delicious eateries often frequented by locals in the know.  I read about Dan & Louis Oyster Bar in downtown Portland and when we walked right by, the decor was so intriguing I had to check it out!  They are very serious about their oysters here.  We had a sampling on the half shell and my very first oyster stew.
