1975–2005
1997-2005
In 1997, the logo was tilted and as a result, the logo looks like it's slightly altered. This logo is still used at locations that didn't upgrade their signs to the newer one. This logo is also used in the Mexico chains.
2005-present
In 2005 the shape was changed and the "El" was squished next to "Pollo". The background was changed to flame with a chicken on top.
