Breakwater (Town Wharf)
Rosie's is unique for a couple of reasons. First, it is the furthest east hot dog stand in the United States. Second it's probably the only hot dog stand serving actual stone ground mustard - the same factory mustard that used to be added to the canned sardines that were processed in the area.
Their dining room is kind of unique too, a picnic table overlooking Eastport's working harbor and the town wharf.
Their hot dogs come with or without chili. I did one with factory one mustard and one chili dog, the hot dog sitting on a good sized bed of chili with beans.
The buns are the traditional Maine hot dog buns that are also used for lobster rolls.
