Sushi bar at Morimoto Asia

Is the sushi bar on the 2nd floor at Morimoto Asia part of ADR’s or is it all walk-up? Anyone with experience sitting there? Also, I know there is a small bar just behind the check in desk at the main entrance to the restaurant. That’s the only bar area in there, correct? Considering my options for a quick bite without an ADR.

I ate there (it was excellent) but did it as a walk-up. I’m not sure how it works with regards to an ADR.
