Do you miss McDonald's and Burger King? No, of course you don't. That's absurd. But if you crave the experience of chaotic counter staff, ignored modification requests, squashed buns and too much "secret sauce" then you are going to absolutely love Earth Burger.
I tried both the classic Earth burger and the spicy "chicken" burger and they were both ... not bad. If I ever find myself again at the MoA, and I don't want to spend the time to have a pleasant dining experience, I would definitely order another Earth burger.
