Crowning the best hamburger is nigh impossible in this beef-crazy town, but a master of burger basics muscled its way to the top of our list. Dairy-ette, the East Dallas drive-in burger joint, has earned serious street cred since opening in 1956. Car hops serve juicy, old-fashioned hamburgers, fresh-cut french fries and homemade root beer to people in cars parked under the red-and-white striped awning. Top a burger with cheese, chili, or live large with chili and cheese. Heck, go for the double meat layered with bacon and jalapeños. Hot grub and sandwiches are also dished out inside at the counter, near the original soda fountain. Root beer is sold by the gallon for $4.50.
