""Breakfast Served All Day"" (meaning any time before 4 or 5PM) says it all. It's a down-to-earth diner, which on the west coast doesn't imply anything about railroad cars, just that they have a griddle and serve lots of eggs. The food is okay. Better than some. On the plus side it's open very early (6AM -- few people are awake by this time on the west cost) so if you are visiting and have jetlag, it might be the place.
Pros: Unpretentious, Open early, Inexpensive
