Mackinac Island does not offer very many options for those who wish to eat something healthy on vacation, but 21 Speed Grill delivers what the health-conscious crave. The prices are not unreasonable, but they are on the higher side. It's set up very much like a Panera where you order at the counter, and the meal is brought to you at the table. The atmosphere is much like an airy cafeteria with a great live musician to entertain you while you eat. I got a salmon wrap, and I did notice that one of the pieces of lettuce in my wrap had gone bad, but overall the quality was great--not spectacular.
