My very first experience with Sonic was the Gilroy, CA location. I wasn't that much of a fan at that point. Food was salty/burned and the staff was less than desirable.
I have to admit my Las Vegas experiences with Sonic have been way better. The staff at this location has always been super nice to me. My usual order includes a Chicken Sandwich, Fries/Onion rings, and milkshake of some kind. It's standard fast food fare, but I do enjoy the "car-hop" feel
