Raye's Old World Gourmet. ^ BEST mustard I have ever had. Great on eggs, sammies, you name it. Wife and I have visited Maine 5 or 6 times now and we always come back with some Raye's for personal consumption and for gifts.
Eastport area is beautiful to visit, Raye's is about the only "tourist trap' found there.
