Must be because of
free dining in October or more people going then but DW and I were there last week and walked in to Via Napoli at 1:00 and were seated immediately with a lot of empty tables around us. We went back two nights later at 7:00 and once again seated with no ADR's immediately.
Granted it's not CRT or Le Cellier but we noticed a tremendous amount of open tables last week and a ton of walk ups being seated fast with no ADR's.
We ate at Tony's, Rose and Crown, Tokyo Dining, La Hacienda, and Via Napoli. The one exception of course was O'hana's where with a 6:20 ADR
we were not seated until 6:45 which was okay because we wound up with a window table and a view of the castle.
