To my knowledge, they have vegetables and salads but nothing specifically vegetarian.
House and Caesar salad are about it on the menu. But presumably they could leave the meat or seafood out of most of their meals. And they have vegetable side dishes.
Only a regular salad, I think. However, you can google " Exit Glacier Salmon Bake " and get a full menu.
