A Hamburger Today has their list of the best burgers. Here is the first half of their list:

Primanti Bros.

Phone: 412-263-2142

The Skinny: They put fries on the burger here.

Rosebud Steakhouse
Address: 192 East Walton Street, Chicago IL 60611
Phone: 312-397-1000
URL: http://www.rosebudrestaurants.com/rest4.php
The Skinny: Thick 12-ounce burger served on a grilled-pretzel roll. Sokolov finds the bun an "eccentric distraction."

Louis' Lunch
Address: 261-263 Crown Street, New Haven CT 06510
Phone: 203-562-5507
URL: louislunch.com
The Skinny: Claims to be the birthplace of the burger. The fact that its sandwich is served between two slices of toasted bread provokes endless debate among hamburger semanticists. Don't ask for ketchup here!
