I may have mentioned this up thread, but I asked two different front desk agents, and they both said the credit could only be used at Suns Out Buns Out, the Kitchen, and Agave.

You can track your spending on your account on the TV and check out on the TV.

We spent like $87 at agave on the day we checked in and when I looked at the account on TV, the next day, it just said $37 agave spend, so I knew the credit was applied.

It didn't specifically show "$87 minus $50"

Ate at Kitchen the next day, $50 credit was automatically applied too.

The mystery though is . . , what if we have eaten there on check out day (Day 3 of two night stay)? Is the system smart enough to reject a third $50 daily credit on a two night stay? It should be. And note the first check in agent I talked to suggested the credit couldn't be used at all on check out days, even if you didn't use it on check in day. But the second check in agent said that wasn't true, it could be used on any two days of my stay.
