Where is a good, inexpensive restaurant for breakfast/lunch in Berkeley or Oakland?

I travel once a month from Watsonville to San Rafael. Sometimes I stop for breakfast, sometimes for lunch in the Berkeley/Oakland area. I don't want to eat at Burger King off the highway anymore, but I don't know where else to go. I have read reviews on the net and found a bit of information here on Answers, but I'd like to hear from Berkeley/Oakland locals who really know what's good. I'm looking for tasty, quality food - not too pricey - I know...it's hard. I did find ONE last time I took a chance. It was called the Royal Cafe, I think. I'm looking for other places though, in addition to that. Thanks!
