Time to resurrect this one.

Amy's in Eureka, CA. Breakfast and lunch joint that doesn't open till 11.
Small place, husband and wife are the only employees. Killer homemade biscuits and gravy. Among the best I've had. Everything else I've tried is top notch as well.

Update: Long time (30 years) favorite #1 Katrina's in Auburn, CA has changed ownership and unfortunately their B&G have suffered greatly. No longer on the list at all.
