This Zagat-rated franchise is famed for one thing: juicy, greasy, homemade burgers, served with an unlimited amount of free toppings, some of them more unusual than others (think jalapeno peppers and grilled mushrooms). The menu is limited, but focused, and meals can be ordered with a huge portion of "Five Guys style" or Cajun fries cooked in 100% peanut oil. Hot dogs any way you want them—bacon, cheese, veggie, kosher—are also available. While waiting for your order, snack on free ballpark-style peanuts stored in barrels around the restaurant.
