Well, I don't think Two-B (NW corner of 2nd and Brannan) is going to open very soon. The event they hosted was a fundraiser for another group, not a pre-opening get acquainted party. There were appetizers, but they may have been catered. The website is still advertising for a Chef. I wouldn't hold my breath.
On the other hand, Koh Samui Thai on the SE corner of Rich and Brannan looks like it is going to happen. There are construction crews there every day remodeling. One can see the outlines of a large, curving bar, the room is pretty big, and "Koh Samui" is the name of an island resort, so I expect this will be an upscale place. I am going to watch and see what happens.
