Johnny’s Fillin’ Station has come a long way since 1985, when it first opened its doors as a frozen lemonade stand named "Lemon Splash." Decades later, the neighborhood staple has traded the lemonade for what’s widely considered one of the best burgers in the 407 area code. Now a beloved local hangout, Johnny’s is marking its 41st anniversary with a massive Battle of the Bands bash right in the parking lot.
