I'm intrigued and would like to try a couple of these places out. Unfortunately I am an hour away in the East Bay, north of there, and so would like to ensure that I'm there during 'the right time" of day. So the drive becomes the gating factor. That is, is any time of day ok / best time to be there. What times would be useless, or a disappointment. Same with days of the week. Is any day good, or are weekends, not as good etc. Seems like being there when you can get a wall seat is desirable too. Can some folks with experience of these places fill in some of the blanks. Sounds also like you need to arrive with lots of $5's, or can you change a bunch of $20 there?
