No. You might as well be a walk in.
Oh well! Maybe another will become available.
keep trying! good luck
my opinion, grab the one with less people and keep trying get to find another with a few as well.
ie: you have 8 people, but you find an ADR for 4... Grab it and keep looking for another one for 4 OR see if you can nab 2 more ADRs for 2. All around the same time frame.
If you all show up together and your ADRs are within the same time frame (say half hour) you will probably get seated together.
Just my humble opinion.
