While Meatheads is more expensive than McDonald's, it's also higher quality food, has better service, and the whole place just has a better design vibe. I'm willing to pay a bit more for that.
They are great about gluten free. I have never felt sick after eating here if I tell them about the sensitivity when I am ordering. It's nice to be able to go out with my family to someplace that isn't really expensive. Places that offer gluten free are usually high end, and they are few and far between here in town.
