https://www.houstonarchitecture.com/haif/topic/16420-locations-of-the-old-princes-drive-inns/Prince's, which helped popularize drive-ins in Texas, was founded in Dallas in 1929. Founder Doug Prince opened his first Houston location on Main Street in 1934 after discovering the magical, easy-to-make hamburger at the State Fair of Texas.
At its peak, Prince boasted 18 stores across the Houston area. It's likely that a visit to Prince's ignited burger love in many that lasted decades.
There used to be one on the corner of Westheimer and Montrose where the gas station/convenience store is now. It went down in the 1980s, I believe.
