Since I was staying in hotel that was remarkably like a dungeon, I ate out for every meal.
I've never done a restaurant recommendation on this site before, but if you are in Grover Beach and want some great American comfort food, try Lil'Bits Cafe. The biscuits and pancakes are made from scratch every day and everything is the best quality.
The people are nice and the coffee is good, too.
Lil'Bits is at 151 N 7th street in Grover Beach.
