Sonic Drive-in? Not in Monrovia.
Sonic Drive-in does not exist at this address in Monrovia. I drove to this exact address and it is an industrial park, never has there been a Sonic at this location. The telephone number is not Sonic's also. I really love their food, great selection to choose from for a fast food place. Too bad there aren't more in Southern California. Believe me, if it was there, I'd know about it!
Retro-outfitted servers deliver burgers, malts and sandwiches to your car at this '50s-style drive-in chain.. In Short Founded in 1953 as a hamburger-and-root-beer stand, this nostalgic eatery is known for its intercom ordering system and roller-skating carhops. While servers rarely roller skate anymore, the famous made-to-order, all-beef burgers and thick malts are still menu favorites. Other signature items include Toaster sandwiches (made with thick Texas toast), extra-long chili and cheese hot dogs and hand-battered onion rings and tater tots. Desserts include chocolate, vanilla and strawberry shakes and fresh fruit slushes.
