In June, food truck park Screamin’ Chameleon quietly opened a stone’s throw the main gate of Joint Base San Antonio-Randolph. While that brings more adventurous eats to the the northeastern burb of Universal City, it also makes the new spot easy for city residents to overlook — and that would be a shame based on Screaming’ Chameleon’s easygoing neighborhood vibes. The unassuming property sits on a quarter of an acre at 122 W. Lindbergh Blvd., giving it space to accommodate five food trucks.
