This place is in the same strip mall as Smoothie Operator. You enter in the same door for both of them, then Smoothie's is to the right and the health food store is to the left.
On a cross country road trip, I took a break from the highway to load up on vegan essentials here. It's a small store but well-stocked. I was impressed with their helpful staff.
It's only a mile or so off the highway and very easy to find. Watch out for the one-way streets once you hit downtown Bismarck. Plenty of parking.
