Due to loose copyright laws,^{[citation needed]} KLG's branding heavily imitates that of KFC. These can be shown through multiple ways; KLG's menu is similar to KFC's, with fried chicken, french fries, chicken burgers and soft drinks. The lettering of KLG also uses the same font and colour as KFC and the logo depicts a plump chicken wearing a bow tie.

Outside of its home country of Taiwan, KLG has operated outlets in Mainland China, Malaysia, South Korea, Thailand, South Africa and the Marshall Islands. In Malaysia, there were several outlets in Ipoh, Penang (near Farlim) and Langkawi Island. On the Marshall Islands, several outlets were known to exist near the country's capital, Majuro.
