No pics but went by yesterday and a MX was charging. Only vehicle charging while Atascadero had 6 of 8 occupied. Sadly only a couple of food choices available within walking distance.
Jack in the Box
Subway
The Slice - Pizza, Beer, arcade. Never been, can't offer an opinion. Google shows 4 stars with 217 reviews.
Starbuck's
If you don't mind eating in the car there are several fast food places down the road at Hwy 46 east and Hwy 101 intersection. Go east from the 101 about a block. Carl's, McDs, Denny's, Taco Bell, KFC. A couple of independent places with decent food. Parking and access can be a drag but doable.
