Fabulous Fern's doesn't have a very good menu for vegans. Certainly, no marked vegan items. After visiting several times, I finally found a server who was super nice and wrote down a nice list of options for me.
The spicy green beans (made in oil/vinegar, not any other sauces or butter), bean dip (no cheese), chicken wild rice salad (no chicken), veggie greek salad (no cheese, kalamata oil dressing) are all vegan options with the noted modifications. The portabella sandwich with no cheese or the veggie burger are vegan -- but the BUN IS NOT VEGAN. She recommended adding fruit or steamed veggies instead of the bun. Finally, the only item on the menu that is vegan without modification is the strawberry spinach salad. It's good, but not satisfying nor filling. I recommend adding some cucumbers or green beans.
All of that said, Fabulous Fern's would get a perfect review if they had vegan buns and marked vegan options on the menu!
