Lucky Chances in Colma's easiest to get to. Bay101's in San Jose. Bay101 is supposed to be a lot nicer but if you're like me and can't afford a garage(e-gads I hate this city sometimes), then Lucky Chances is better for that reason alone.
But Bay101's best feature apart from being home to a WPT event is that it's really close to Great America. That way if you lose a tournament, at least you can console yourself with funnel cake and rides.
