I've only been there a couple of times, but the new Brenda's on Diviz easily has the best breakfast in the neighborhood. (It's nice to have the jam in a container on the table, not in those little plastic packets.)
My only gripe: the volume of the music. This is a mystifying but common practice in busy local restaurants. When the place is crowded with talkative people already struggling to be heard over the din, why insist on background music at all? I love the blues, but not cranked up to white noise level in an environment where conversation is already difficult.
Michael Bauer's review in this morning's Chronicle gives Brenda's the maximum four bells noise rating, which means diners "can talk only in raised voices."
