Known as “the jewel city,” Glendale CA is one of the largest—and some would say most pleasant—cities in Los Angeles County. From Glendale CA’s Forest Lawn Memorial Park, where many celebrities from the golden era of the silver screen are buried, one can view the cityscape against a backdrop of gently folded foothills. One of the most well-known facts about Glendale CA is that it has a thriving Armenian community. Glendale CA is also known for its many food companies including Nestle, IHOP, Baskin-Robbins, and (historically) Bob’s Big Boy.
