The Beausejour Dairy Bar is an institution in this small town. While the main draw is the ice cream, they also have some great eats. I never pass through Beausejour on my way home from the Whiteshell without stopping for some food or a "scream" (ice cream) as the locals say.
The ice cream selection is out of control, so many options. There are a few nice places to sit and is just generally a quaint place to stop en route home. It is cash only so remember that and there is always a line-up, but be patient, it moves fast! Enjoy your food and ice cream and prepare for the journey home, unless of course your from town!
