Five guys makes awesome burgers. EXCEPT, they use yucky cheese SLICES instead of real cheddar. And I'm sorry, but for $1 extra there's no excuse for not using real cheddar. Americans love their American cheese (which is what Kraft singles are).
Also why aren't we getting milkshakes? I would live that.
Also, adding onion rings would be awesome. They are very hard to find on moat menus these days!
Staff are always great and friendly.
