Had the opportunity to eat at J's Oyster with my wife and another couple visiting from NYC. After a dozen oysters and a Haddock sandwich all washed down by two Allagash White pints on tap, the husband proclaimed it the greatest lunch he had ever eaten. My six oysters and another Haddock sandwich impressed me likewise. The oysters were fresh - could have been more briny to my taste - and the Haddock was a meaty fillet cooked to order.
With oysters only $13 a bakers dozen, J's is a real bargain and should not be overlooked for a great lunch place in Portland, especially in the summer when they put out in the back a few tables lining the wharfside.
