I have incredibly high standards for burgers. In N Out is my favorite. So you could imagine my surprise when I tried Easy Street Burgers and fell madly in love. Single Smash Burger: Single Smash Burger begins with a 100% pure beef patty smashed and American cheese, seasoned with just a pinch of salt and pepper between Martins famous potato rolls. Choose your toppings of tangy pickle, chopped onions, ketchup, mustard, and our special wild sauce. It contains no artificial flavors, preservatives or added colors from artificial sources.
