Try the one and only Culver’s for one outstanding Hamburger or any other item on the menu.

Culver’s makes some of the best fast-food fried chicken going. It beats the heck out of KFC, Browns, or Church’s, and comes within spitting distance from some of the fried chicken restaurants I know.
Tommy’s Chili burgers, the original on the corner of Berverly and Rampart.
The best chili burger ever made...go there at 3am and there is still a long line.
