Open 24 Hours & Better Than Denny's!.
For Rocklin all-nighters, you have two options: Denny's or Mel's Diner...take your pick! Denny's is more visible and located right off I-80 and Rocklin Road and Mel's is off Hwy 65 and Blue Oaks (near Chevys and Carls Jr.)
Burgers...they're okay if you compare them to Denny's, but compared to non-24-hour-joints, they're pretty mediocre at best.
Chicken Quesadilla...it's usually pretty good (I get it on a wheat tortilla) but the salsa leaves a lot to be desired (think Pace with less flavor).
