Strong tangent here, but y'all vegetarians in the Bay Area ought try Dad's Luncheonette in Half Moon Bay for their mushroom sandwich, a vegetarian's alternative to the hamburger sandwich.

I got no affiliation with Dad's aside from thinking that they make a couple of fine sandwiches, and the mushroom sandwich is a great example of a vegetarian hamburger "alternative" that doesn't try to be a hamburger but tastes real good.

I'm omnivorous but like that mushroom sandwich sometimes (and the hamburger sandwich they sell is probably the best sandwich in the state, so that's saying something).
