There aren't that many restaurants in Ludington where one can get good vegetarian/vegan food, so we come here a lot :) They usually have 3 or 4 vegetarian entrees available, but they are not all listed on the menu - you have to ask for a separate menu or ask the server to specially tell you the veg features. This is the only downside to me, because when we are out with omnis it just makes me stand out more to have to ask specially for the veggie menu. Also, when we were there last, the hostess had no clue about the veggie menu when I tried to ask for it while being seated.
Sometimes they will also have one vegetarian pasta and one or two vegetarian/vegan salads or soups listed on the menu (the menu changes frequently though). Veggie sushi is almost always available which is great and we get it a lot. They have an outdoor/rooftop seating section in the summer which is fun, but to my knowledge the veggie options up there are pretty much limited to one vegetarian sandwich, a plain salad, hummus with pita and veggies, fries, and the veggie sushi. They used to also have a black bean burger but didn't have that this summer. Overall though the Blu Moon has the best and widest selection of veg-friendly food in Ludington.
Cons: Have to ask for the veg options
