OK. Most meals in SF area are good, sometimes overpriced, sometimes the staff in dreadlocks etc, but generally not disappointing if you're not overly primed for the time of your life.
On the other-hand there are utter frauds. Restaurants who expect the tourist to arrive once. there only responsibility is to charge high prices, look pretty, so the customer doesn't leave at once, say some nice things to Michael Bauer, so that he's overcome by it's authenticity [Nixon ate here]. (I could name a few in Berkeley, but you'd have my head)
So how about a heading or just a thread of early warning system. Those joints to avoid at any cost. Call the thread "treat it as radioactive" Blessed by such good choices, the list would be small, decisive and easy to reac.
