Sonic Burgers Opens in San Marcos

Sonic Burgers, in a return to the 1950’s, offers dine-in-your-car service, ordered through a loud-speaker, with your food delivered on roller skates, with a coin changer on their belt. Known throughout the South, but relatively rare in Southern California, this chain is known for its milk shakes, tater tots, limeades and burgers. This new San Marcos location (only a block away from 5 Guys Burgers) at the Hwy 78 Las Posas exit has been causing traffic jams for the last two days.
