Yak and Yeti is likely more willing to be flexible. They are not Disney owned, they are Landry. They do many things different. Like take walk ups, take their club card members over ADR people, etc.
So yeah, wouldn't surprise me at all that you can go to the bar and order something to go.
DH and I eat there most every trip and we always opt to sit at the bar. No ADR needed, just an open seat at the bar. Not hard to find so we'll just check in as we pass by and grab seats when we see them.
No idea if any other restaurant works that way, even if they have seats at the bar.
