@kmorlock Touring Plans has a dining res tool. Sign up for a free account, you have to jump through a few hoops to navigate to it vs the paid membership. Then you can set up two separate "waitlists".
Here's the kicker though...you have to be lightening fast when you get the text with link that it matched something for you.
I received notifications several times, and finally was quick enough to get the BOG lunch res that matched. Once you get that notification it deactivates the search so if you don't get it you have to go back in and restart it.
