Nothing available when ADRs opened up, but 2 days prior, I was able to get a table for 2 and a table for 3 at the Lounge for the same time. A lot of people switch around their plans close to the date.
I will mention that we had had lunch at the restaurant a couple of years ago, and I don't think we spent that much more at the restaurant than at the lounge. Those apps do add up, and they are individual portions. Just mentioning that because our main motivation for getting a Lounge reservation was because everyone says it will save you $$$$$, but it was still very pricey and not a large savings over the restaurant (at least at lunch).
