I had guests in from Ontario, from the part of Canada that is south by a long drive from Duluth. We talk often about that oddity, about how strange it feels to drive north to the United States from Waterloo.

They wanted to know what eateries had opened in Duluth since their last visit. I took them to Northern Waters Restaurant in the Mount Royal Shopping Center, where we enjoyed a two-hour lunch.

There are two joys about eating at Northern Waters. One is the unique pricing. Tax and tip are rolled in, so I never worry about whether my companions tip well enough, or whether I tip well enough. That is a greater relief than I expected.

The more substantive dimension is the food, of course. I had the sandwich with the catch of the day. It was a herring sandwich, and I ordered it with a sense of adventure. My whole life, my only experience of herring was pickled, typically stabbed with a toothpick and put on a cracker. I giggled nervously as I ordered it. It was so very tasty.
