Review of Burger 21

Staff was knowledgeable. I skipped the fries since I'm paranoid. I don't eat out much at all so this was a leap. Burger was good (not amazing but good), milkshake was delicious. Food was brought out separately and marked. They said they make the milkshake with a separate spindle to avoid cc. Good experience, didn't get sick.
